Oddly, it was the "grassroots" that got Bush in office by sheer numbers of voting (if he didn't have truly enough to win, he at least got enough that it was easy to fudge). There are many people in this country who make low salaries who, for some reason, support the Republican Party when it is no longer in their best economic interest to do so (once upon a time, it WAS the fiscally conservative party). I think their thinking is "Dad/Mom voted Republican, we've always voted Republican" without thinking about WHY they used to vote Republican.
