Regarding a republican primary contest. Sure, the poll may have issues, but this is making an impression in the repub political world. This is a small sidebar in the greater picture, but is nonetheless important imho, because it represents the first clear evidence of being anti-Mitch rather than anti-establishment/Dem etc as a winning strategy. Remember the tea party.
The dems could do well to take note, given how clearly the repubs have portrayed Pelosi.
