A new survey from PPP (PDF) shows that 26% of Americans, most of whom are Republicans, think that ACORN stole the election for President Obama.
For the sake of comparison, a Gallup poll immediately following Gore's concession in the 2000 election showed that 18% of the county, a significant percentage of whom were African-American, believed that Bush stole the election.
In 2004, the numbers for Bush were even lower. Back then, in the wake of Kerry's concession, a Gallup poll showed only 13% of the country believed that Bush stole the election. (FWIW, I was among the 5% or so that shifted from 2000 to 2004.)
This is simultaneously a demonstration that hard-core conservatives live in an entirely different reality than the rest of the country, and that the hardcore conservative base is as much as twice as large as the hardcore progressive base. As both a media figure and a political organizer that operates primarily in the hardcore progressive world, I'd be lying if I didn't admit the size of the hardcore conservative base made be pretty jealous.
With the exception of 1995, polling has consistently shown that there are more Americans who believe Republicans are too liberal than there are Americans who believe Democrats are too conservative. Further, a larger percentage of Americans are Republicans who would prefer less-electable candidates with whom they largely agree on issues, than are Democrats who hold the same belief (source, PDF). And there are even more conservatives who think the 2008 election was stolen than there are progressives who think the 2000 election was stolen, which is pretty remarkable given the difference in margin between the two elections.
Many dismiss the importance of an active, engaged, ideological base, but such a base seems to have far more benefits than negatives. The base provides the resources to win elections. They provide turnout in low attention and enthusiasm elections. They fuel the primary challenges that keep party members in line, and thus allow you to pass legislation. They make your entire party appear to believe in something, rather than being wishy-washy and attempting to win for its own sake. The continuing base gap between conservatives and progressives is a major factor in why progressive governance remains so much more difficult than conservative governance.
