The problem for the Democrats in Arkansas is that the state is strongly against healthcare reform (only 35% support, it according to surveys). It is likely to be a similar theme across the country in those "purple" states.

Primaries are part of the tools of American democracy

One of the many things I wish we'd replicate from the US political system.

allowing a surprise victory by a Democrat (see: NY-23's special election last year).

I just hope the Tea Partiers have learnt from that. Better the devil you know.

This would drag the Republicans, as a party, even further right.

Would it? If you strip away the fringe elements of the Tea Party, the "birthers" et al, you're left with a group that seems to me to be libertarian. Scott Brown was, after all, a Tea Party favourite and he's considered to be a left-wing Republican.

Which may ultimately lose them votes among Independents who usually vote Republican

Not sure that's true. I'd guess that most independents who vote Republican do so due to them being considered the party of low taxation. What the Tea Party folk are saying is, the Republicans have lost sight of that philosophy of fiscal conservatism. If anything I suspect the Tea Party might move the Republican Party into the centre and gain them more independent voters, not less.

Hoo boy, both the Senate race and the Gov. race out here are going to be interesting to watch, especially the Republican primaries for both. My guess? Meg's got a better shot than Carly, because EBay didn't get destroyed the way HP did.

Just my guess, though.
