What numbers? Not to be counter productive here, but it would be foolish to suggest that the majority of Americans are generally happy with the performance of the GOP since the 2004 election. Almost every analysis I have read suggests that we will lose seats in both houses.
LOL. They said the same thing in '04 :)
Well, I don't know what you've been reading. The GOP is not doing well in approval ratings. But it's still doing better than the Dems. And the generic Dem vs. Rep numbers I've seen are about the same as they always are - favoring the Dems by 5-9 points. When you factor in fundraising, blue state vs. red state seats being defended, a powerful fundraising tool in the POTUS, and the high winning percentage of incumbents, I can't realistically envision a scenario where the Dems regain either the House or the Senate. Or make significant inroads in governorships.
People are unhappy with the GOP until they see what the alternative is
