Six votes isn't much, given that Virginia, Colorado, and Nevada are evincing such a trend in the opposite direction.
You mean by electing a really conservative Republican governor in 2009 and three new Republicans to the House in 2010?
Well, touché, but Colorado and Nevada are anyway 15 votes.
You can’t count Colorado or Nevada as reliable Democratic states. Obama won them when the Republicans were just a few percentage points more popular than lung-cancer, and the economy seemed to be collapsing. If (and that is a big if) the GOP nominates someone else than Palin or Gingrich I can easily see Colorado and/or Nevada going red in 2012.
My point is that nothing is certain yet.
Safer than Iowa and New Hampshire now, and perhaps Pennsylvania and Wisconsin, in view of their 2010 votes.
