A Sarah Palin Presidential bid would certainly make history- in all of the wrong ways for Republicans. PPP has polled the 2012 Presidential contest in a dozen states over the last two months and in 9 of those Palin would lose by the biggest margin of any Republican Presidential nominee since Barry Goldwater...or even further back. In a few of those states you have to go back to the days of Harry Truman and Franklin Roosevelt to find a GOP nominee whose margin of defeat was as great as Palin's current polling deficit.
Here's how it breaks down-
States where Palin's current deficit would result in the biggest loss for a Republican candidate since Barry Goldwater and 1964:
-Nevada where she trails by 13
-Pennsylvania where she trails by 15
-Ohio where she trails by 7
-Wisconsin where she trails by 14 (John McCain lost by a similar margin)
-Minnesota where she trails by 18
-Michigan where she trails by 21
Barry Goldwater did comparatively well in the South (at least to how he was doing in the rest of the country) so in a few states that Obama flipped to the blue column in 2008 you have to go back even further to find an election where the Republican nominee did as bad as Palin is right now:
-Her 14 point deficit in Florida would be the worst for a Republican since Dewey didn't defeat Truman in 1948.
-Her identical 14 point deficit in North Carolina would also be the worst for a Republican in the state since 1948.
-And the big winner is...Virginia...where Palin's 11 point deficit would be the worst for a Republican in the state since FDR's final reelection in 1944.
In the other three states we've polled Palin does worse than John McCain in 2008, but at least outperforms either George Bush or Bob Dole's performance against Bill Clinton in the 90s. Her 2 point lead in Montana would be the worst for a Republican since Clinton won the state in 1992. And although she trails by 3 points in Missouri and 29 points in Massachusetts, Clinton won those states by larger margins in 1996.
In any event Democrats should be rooting like hell for Palin's nomination.
