The tea partiers just put an 11 point underdog into the race in Delaware, by defeating an 11 point favorite.
You just hit on the crux of problem. If there is little difference between the winner and loser of a primary, then the winner will have no problem picking up the votes of the loser in the general election. However, this not the case with most of the tea party candidates.
While a victory for a tea bagger in a primary may energize the far right, it is also likely to energize the left. Since Tea-baggers will need the support of moderate Republicans and often conservative Democrats, a Tea-bagger victory in the primary is not necessary a good thing for the Republicans in the general election.
Although Republicans could win the House, I think they have lost the Senate.
You guys all miss the point. The Tea Party is not by default Republican. It is A grass roots conservative movement. It's goal is not to hand the Republicans Majority's, It is to Force the republicans back to our values.
It appears to me that you people are so wrapped up in Party politics you can not fathom that so many people are choosing Ideology over Party for a change.
Regardless of the outcome it is very refreshing to me.
