No: Clinton won partly because he was able to pull the Democratic party significantly to the right of where it had been before. And even then, the Republicans made huge gains in 1994.
No, Clinton was a hardcore liberal in 1992, and then when the Republicans won in 1994 he claimed their platform as his own just so that he could be reelected.
That's a laughable claim. Even in 92 Clinton was running on ending welfare as we knew it, cutting waste, tax credits to stimulate growth, aggressive crime control, etc. Hardly ideas you'd see the Jackson or Wellstone types proposing.
