Which doesn't look good for Republicans:

Tuesday's congressional primaries provided an astonishing and symbolic coda to a primary season filled with turmoil, infighting and candidates unique in their politics and policies. But rather than providing firm answers for the general election ahead, the win by conservative candidate Christine O'Donnell in Delaware and the very real possibility of Attorney Ovide Lamontagne's victory in New Hampshire raises some difficult questions about the Republican Party's present and future.

With the primaries almost over, eight establishment-backed Republican candidates have succumbed to challenges from conservatives — if Lamontagne defeats Kelly Ayotte, that would make nine — producing a chaos that bred opportunities for Democrats in an otherwise historically awful climate.

Appearing on the Rachel Maddow Show a few minutes ago, Nate Silver of FiveThirtyEight said wins for hard right candidates could cost the GOP in November. Whereas Silver said Republicans had a 26 percent chance of winning a majority of the U.S. Senate before tonight, O'Donnell's win combined with Lamontagne, if he wins too, would reduce their chances to about 15 percent. In other states, Tea Party backed Carl P. Paladino leads in the New York governor's primary—I refuse to write "gubernatorial," sorry—race. The AP has a good run-down of all the major Tea Party upsets this year.
