Perry has fallen a lot, but had a long way to fall, and seems to have bottomed out.
For example, among whatever passes as Conservatives in a WP poll Perry’s favorable/unfavorable is 47/37.
Herman Cain, the “conservative darling? 54/34.
Gingrich on the other hand, is at 65/19. I presume once we get two weeks of stories about all of Gingrich’s actual positions, that will turn around. Because for every false or overblown story about Rick Perry, there are two real ones about Gingrich.
And in the ONE thing that Perry gets reasonable attacked for, the illegal immigration issue, Gingrich’s stated positions were worse.
Of course, Romney is 60% favorable in WP surveys among conservatives, so it probably means that they aren’t all that conservative.
