2006 was as about as bad as it can get for Republicans is Virginia. Even then, Webb only barely managed to eke out a victory.
Wrong. 2006 wasn't as bad it gets for the Republicans. The Virginia GOP was running Macaca Allen, who was and still is a beloved figure in Virginia. Macaca Allen was a top-tier candidate who got victimized by a gaffe.
It has been forgotten that Republicans turned out in force in 2006; they were outnumbered by Democrats and Independents voting together. What's more, Republican candidates held their own in the South.
It can get worse for Republicans than 2006. It's the same way that 2002 was worse for Democrats than 2004.
