The Waves of the GOP Campaign

At The New York Times, Katherine Q. Seelye reports:

An analysis by The New York Times of more than 50 polls between June and last week shows a stark pattern of how voter sentiment shifted in defined blocks, first for Representative Michele Bachmann of Minnesota, then for Gov. Rick Perry of Texas, then to Herman Cain, the former business executive. Support for Mr. Romney and for Representative Ron Paul of Texas remained fairly static.

The Times charts the candates' rise and fall here.
