That tells me that Rodney sees the writing on the wall, and will not be a candidate for the Senate in 2010. It is still possible that he could switch parties at the last moment, much like he did in 2004 to undertake a challenge from the Democratic Party, but I just don't see it happening at this point.
It seems all but certain that Alexander will be facing Andrew Clack in a GOP primary again, though it remains to be seen how effective such a challenge will be. If Mr. Clack can get the Club for Growth folks involved, he stands a better chance of wresting the nomination away from Alexander.
The question then becomes whether there is a Democratic candidate out there willing to challenge Alexander in a general election. There were rumors that such a candidate would emerge during the filing period this summer, but none did.
I wonder if Alexandria Mayor Jacques Roy would be willing to take on this fight. Doing so however, would mean foregoing a re-election campaign for Mayor, which is that fall as well.
