Obama win not a given

The anti-Iraq war group voiced concerns in a video sent to its members Tuesday that progressive activists may turn lethargic if they view as a given a victory by the likely Democratic presidential nominee.

“Barack Obama has generated so much excitement that some progressives I talk to simply think there is no way he could lose, and it's not really hard to see why,” Political Action Executive Director Eli Pariser warned in the video.

“Obama is a terrific candidate and Republicans have definitely made a mess of things. But the truth is Obama also faces some real hurdles between now and November,” Pariser said.

“We can win, but we're gonna have to fight for every vote.”

The Illinois Democrat only has a three-point lead in national polls, said Pariser, who told supporters the race could turn and that anything can happen to a mid-summer lead.

Pariser listed a number of potential pitfalls for Obama that should encourage his supporters to work hard for a win.

Obama has raised more money than McCain and appears to maintain an advantage in cash, but Pariser could be referring to the cash advantage the Republican National Committee has over its Democratic counterpart. When the figures are combined, McCain has a slight advantage, and the GOP funds could also be used against Obama.

Also, because McCain has decided to accept public matching funds, he has to spend all of the money he has raised for the primaries before the Republican convention.

Pariser also said the public doesn’t realize what McCain’s positions are on some issues. Pariser specifically said some believe McCain favors abortion rights.
