A new Zogby poll shows only about a third of Obama's voters supported him because of his backing for an amnesty, while two-thirds either voted for him despite his support for amnesty (15%) or it wasn't a factor at all in their decision (51%). Interestingly, among McCain voters, 59% did it despite his amnesty stance, 28% didn't care, and only 11% supported him because of his backing of amnesty. The respondents overall backed enforcement over legalization by 3 to 1, but they were also asked whether those positions were less important to them than a year ago — 11% of enforcement supporters backed it less intensely than a year ago, but fully 20% of amnesty supporters were less committed.
