John Sides throws a few handfuls of salt at that PPP poll. Sager tries to understand what the poll means:
Both 2000 and 2004 were close enough to justify some amount of paranoia. Now, perhaps, the Republicans are paying back the Democratic conspiracy mongering of the last decade with their own childishness. ACORN is the GOP’s Diebold, maybe. “Barack Obama is illegitimate,” is the Republicans’ version of “George W. Bush is going to suspend elections in 2008 and seize power as a dictator.” The difference, though, would seem to be how widespread this stuff is. I haven’t seen good polling on how many Democrats bought into the crazier theories during the Bush years, but it couldn’t possibly have been this widespread. Could it have?
