From NBC's Chuck Todd
The first test of a Mike Huckabee in the post-Mitt Romney world as a conservative alternative to John McCain comes in Virginia. It's a fascinating test, frankly; Virginia's Republican electorate could be much more conservative than folks realize.
Why? The presence of Barack Obama, who has been a magnet for independent voters. Virginia doesn't have party registration; many a moderate indie or even a very moderate Republican from Northern Virginia could decide to vote in the Democratic primary race. Virginia has a decent sized evangelical population and no doubt Huckabee has tapped into those folks already.
Sure, there's a sizable veterans population that McCain could do well with, but keep an eye on Tuesday's Virginia primary; it's Huckabee's last chance to prove he can beat McCain somewhere.
Sure, it's a Southern state, but it's one that allows indies to crossover and would be a blemish on McCain if he lost. Frankly, it's probably Huckabee's last stand to prove viability as a serious alternative. If he can't win under what may be ideal circumstances for his campaign; then next week may bring another exit from the race.
