Hard to say. It actually doesn't feel that way right now, for a couple of reasons:
(1) right-wing nutcases, just like everyone else in the country, are reminded on a daily basis just how badly the Bush administration has failed: gas prices twice what folks are used to, and food prices through the roof. Whether the Iraq situation bears ultimately on the price of gas or not, average folks are reminded of a general malaise resulting from oil dependency, and a failure of policy in Iraq, on a very, very regular basis. It's hard to be righteously indignant and a nutted out nationalist religious freak when your Freak In Chief, George Bush, put you in this position
(2) Obama has made it very clear that he is going to take on the right-wing smear arguments. In his acceptance speech Tuesday, he directly addressed the fact that Republicans will try to use religion as a wedge, will try to create fear about the middle east, and will attempt to divide the country. He is not only willing but eager to take that point of view and shove it right back down their hypocritical throats, and it is going to be very entertaining to watch McCain twist in the wind as he becomes more desperate and thus prone to such (absolutely typical) traditional republican smear tactics, which Obama has already pre-emptively named, labelled, branded negatively, and discredited.
One of the (many) appealing things about Obama is that he knows his candidacy is bigger than he is, that it is about something much more than his own record or personal appeal, and for that reason he gets enormous political benefit and capital from staying true to principles. And is constantly rewarded by the electorate for those principles. Great example: now that he's the nominee, he has asked the Democratic National Committee to abide by the same fund-raising rules that he has implemented in his own campaign since the beginning: not a dime from lobbyists, and not a dime from political action committees. The DNC is now forbidden to raise money, even for its own projects and endeavors, through those means. Never in history (to my knowledge) has a candidate instituted such restrictions, and the beautiful thing is that even with said restrictions he has outraised any political candidate in history. Grassroots actually means something here in this case, and it's encouraging to see.
