Bob McDonnell 2.jpgHas it really been a year since the 2008 elections? Compared to those heady and historic days, today's off-year elections are destined to be a let-down. But here are five key races in the South that could help give us a sense of the region's and country's political temperature:VIRGINIA GOVERNOR: For months this was the big race to watch. Now, with Republican Bob McDonnell widely expected to trounce Democrat Creigh Deeds, it's all about spin: How did Deeds come undone? What does it say about the mood of Virginia voters? 538.com thinks the national mood hurt Deeds, but also says governor races aren't a good barometer of political trends. Democrats wonder why Deeds backed away from progressive positions on health care, energy and the Employee Free Choice Act.

Anthony Foxx 2.jpgCHARLOTTE MAYOR: The toss-up battle in this key economic center will measure how well the state's blue turn is holding up post-2008, and whether changing demographics will continue to favor Democrats. Democrat Anthony Foxx could be the first African-American mayor in the city in 22 years. Republican city councilman John Lassiter has a base in the business-friendly white neighborhoods of South Charlotte. Stay tuned.

ST. PETERSBURG MAYOR:
Another toss-up in another swing state. Democrat Kathleen Ford and Republican Bill Foster are both lawyers and both city council members. Ford's campaign has been more grassroots, although Foster has gained the support of the Glenn Beck-inspired Pinellas Patriots, which may reveal how much political clout the tea party crowd can muster.

HOUSTON MAYOR:
It's going to be a Democrat in the fifth-fastest growing city in the country, but which one? The Swing State Project says it's down to wealthy Democratic city councilman Peter Brown and Democratic City Controller Annise Parker, who is making history as the city's first competitive openly gay candidate. Expect a run-off between the two.

MIAMI MAYOR:
Obama might have won Miami-Dade County with 57.8% of the vote, but this year's mayoral race is between two Republican city commissioners: Tomas Regaldo and Joe Sanchez. It may come down to baseball: Regaldo fought to kill a deal to build the Florida Marlins a new stadium in Little Havana with taxpayer money; Sanchez supported it. Unions are throwing their support to Regaldo, especially given Sanchez' plans to close the city's $60 million budget hole by cutting city worker pensions.
