By the numbers, Georgia is the biggest prize this Super Tuesday with 76 delegates. Perhaps most telling will be Newt Gingrich’s performance in his home state: if he wants to stay competitive in the race for the Republican presidential nomination, he’s going to need a decisive victory in the Peach State. Ohio, with 66 delegates of its own, may be the biggest psychological prize. Many have declared this the race to watch, as no Republican nominee has ever become president without winning the swing state in the general election.

Today in India an explosion tore through an Israeli diplomat's car on the streets of New Delhi, Israeli officials said. The driver and a diplomat's wife were injured.

At least five people are dead and many are injured after storms hit the nation's southeast. South Carolina, Georgia, Louisiana, Alabama, and Mississippi were all slammed by the severe weather and suspected tornadoes. Thousands remain without power. Derrick Becker, a public information officer for South Carolina Emergency Management, talks about what his organization is witnessing.

On Tuesday, federal agents arrested four men ranging from ages 65 to 73 from the north Georgia towns of Cleveland and Toccoa on charges of an ambitiously designed domestic terror plot. The men are accused of trying to procure 10 pounds of ricin — an extremely lethal biological toxin — as well as explosive devices and illegal firearms. Kim Severson, Atlanta bureau chief for The New York Times, reports on the latest.

At 11:08 PM on Wednesday, Troy Davis was executed by lethal injection in a Georgia prison. Davis, who was convicted of murdering an off-duty police officer in 1989, maintained his innocence until the end. His case drew international attention after questions arose about his conviction, including 7 of 9 eyewitnesses recanting or changing their testimony. Prominent groups and leaders from across the political spectrum called upon the courts to review his case. The Supreme Court reviewed by denied a petition to stay his execution.

A last minute appeal to the U.S. Supreme Court was not enough to save Troy Davis. The Georgia inmate was executed for the murder of a Savannah police officer, despite serious doubts about the evidence against the 42-year-old. Davis's case gained the support of hundreds of thousands of followers, including former President Jimmy Carter, Archbishop Desmond Tutu, former Republican presidential candidate Bob Barr, and celebrities like Sean Combs and Cee-Lo Green. 

Troy Davis is scheduled to be executed tomorrow night after having been on death row for two decades for the murder of Savannah, Georgia police officer Mark Allen. His family, friends and supporters worldwide — including Rev. Al Sharpton — are fighting desperately for his clemency. The Georgia Board of Pardons and Paroles may make a decision today on whether Davis will live or die.

Melonie Ware was a daycare provider in Georgia who was sentenced to life in prison for shaking a nine-month-old baby to death in 2004. But in a 2009 retrial, a court declared that the medical examiner's findings were insufficient, concluding that the baby most likely died because complications due to sickle-cell anemia, and acquitted Ware.

Doctors have credited hundreds of untimely infant deaths to shaken baby syndrome over the years. But more and more, medical experts are starting to doubt that baby shaking was the cause of death in certain cases. A new Frontline documentary, airing tonight on PBS stations, examines some of these cases, including Ware's. 

Controversial legislation seeking to address illegal immigration in Georgia has passed both houses of the General Assembly. The bill is does some of the same things as Arizon'a controversial immigration law, SB 1070. The bill allows police to check citizenship status of people pulled over for traffic violation; it also makes it mandatory for employers to check the status of their workers. While Georgia's governor, Nathan Deal, has campaigned on this issue, he may not actually sign it. Melissa Stiers, reporter for Georgia Public Radio has the latest.

Just months before the sesquicentennial of the Civil War, archeologists in Georgia have discovered the location of a stockade used for Camp Lawton, a Confederate prison camp which housed Union prisoners of war.

Yesterday, a Time Magazine article suggested the damage from the Gulf oil spill may have been exaggerated, and that some of the marsh areas important to the Gulf's life cycle may have escaped disaster. But can we know the full extent of the damage caused by the spill, just two weeks after the leak has been capped? The impact of the sheer volume of oil – which on its long journey to shore from the spill site loses some of its toxic qualities in the ocean – has yet to be determined. How can we better understand the complexity of the spill, and the road to recovery?

Ahead of today's primary elections, politicians in Georgia tried to overcome voter apathy with increasingly pointed advertisements and anti-incumbent rhetoric.  

President Obama announced Tuesday that he approved a loan guarantee to underwrite construction of two new nuclear reactors in Georgia.  These would be the first new reactors built in the United States since the 1970s. Will this be the start of a new wave of nuclear energy in this country?

The Bureau of Labor Statistics will release November's unemployment numbers this morning; most observers expect unemployment to rise once again. Millions of Americans are either un- or under-employed, and many are making ends meet with unemployment checks. Some of the state unemployment funds paying those checks, however, are going bone dry. Carl Guzzardi, tax director for the Connecticut labor department, says the state is having to borrow billions of dollars. The Ford Foundation is helping many states overhaul their unemployment systems; Director of Quality Employment Helen Neuborne joins us to describe their efforts. And Georgia's Labor Commissioner, Michael Thurmond, discusses Georgia's attempts to overhaul their unemployment system.

In Atlanta, a hotly contested mayoral race that was almost certainly partially about race drew to a too-close-to-call near-tie Tuesday night. Former state senator Kasim Reed, who is black, and city councilwoman Mary Norwood, who is white, tried not to make race a central focus of the campaign. But in a city where black mayors have been the norm since the 1970's and city residents often vote along racial lines, there was almost no escaping the hot-button issue. We talk to Rickey Bevington, an anchor with Georgia Public Broadcasting.

After yesterday's election, Atlanta Councilwoman Mary Norwood and State Senator Kasim Reed will square off in a runoff to become the city's mayor. If she wins, Ms. Norwood would become the city's first white mayor in a generation. William Boone is a political science professor at Clark Atlanta University, and he gives us a look at the role of race in the city's mayoral contest.

It's election day, and Atlanta may be on the verge of electing their first white mayor since 1969: Mary Norwood, a city council member for eight years. Georgia Public Broadcasting's Susanna Capelouto surveys the scene and the potential for making history and joins us from outside the polls. She also explains why turnout is expected to be as low as 30% today.  

Georgia and much of the Southeast is recuperating from the heavy rains and floods that destroyed homes and cars this week. Ten people have officially been reported dead because of the floods. Georgia Governor Sonny Perdue declared a state of emergency and has asked the federal government for assistance. For an update on the situation, we speak to Susanna Capelouto, news director for Georgia Public Broadcasting, and Angela Olson, whose house was damaged in the flooding.

For many inmates in American prisons, the U.S. Supreme Court is their favorite pen pal. Prisoners have been known to write weekly (or daily) letters begging the justices to intercede in their cases. These direct pleas (writs of habeas corpus in legalese) have been consistently ignored by the U.S. Supreme Court for fifty years. Yesterday, however, the court surprised many legal observers by breaking its long habit and intervening in the case of death row inmate Troy Davis. He has been on death row in Georgia since being convicted of the 1988 murder of an off-duty police officer. Adam Liptak, Supreme Court correspondent for our partner The New York Times, joins us with more of the story.
