Election Day Elsewhere
Virginia and New Jersey will elect new governors while New York City, Detroit, San Diego and other large cities will have mayoral elections. Additionally, there are referendums and initiatives on the ballot in California and Ohio which could have far reaching consequences depending on their result.
Political Wire has a good primer on some of the more important contests of the day.
From an Alabama perspective the race to watch is probably the Virginia's governor's race. Popular Democratic Governor Mark Warner can't run again and the race to succeed is considered a toss-up. However, if Democratic candidate Tim Kaine emerges victorious it will give Democrats (especially in the South) hope that they can rebound against the recent GOP tidal wave throughout the region. While the VA race is not especially analogous to the upcoming Alabama governor's race, it would give state Democrats some hope as they attempt to reverse recent Republican gains.
Of course if GOPer Jerry Kilgore can snatch the Virginia governorship away from Democrats, it could signal that Southern Republicans are still dominant even though the national party is currently beleaguered.
The National Journal's Hotline on Call blog looks to be a good source for results once the polls close.
