According to the Tucson Citizen, Jim Kolbe says that
Graf can't win because his views on immigration and other issues are too extreme for the district.[CD8: Giffords vs. Graf Nation's eyes on CD8 contest BLAKE MORLOCK]
Kolbe's apparent strategy is "An Echo, Not A Choice." But on immigration, the views of Americans in general are more extreme than almost any member of the political class. Someone who promises to actually defend the border will get votes from both Republicans and Democrats. Here's another quote from the article:
Silvia Pereira, 40, a [Republican] precinct committee chairwoman, supported Huffman, but will switch her allegiance to Graf.
Guess what? That's how most voters feel. It's only the "bipartisan" consensus that keeps Republicans from beating Democrats like a drum with this issue. That, and the President's plan for amnesty, of course.
