McCain Leads in Friday Zogby Polling

The Big Mo has suddenly moved to the Maverick:

ZOGBY SATURDAY: Republican John McCain has pulled back within the margin of error... The three-day average holds steady, but McCain outpolled Obama 48% to 47% in Friday, one day, polling. He is beginning to cut into Obama's lead among independents, is now leading among blue collar voters, has strengthened his lead among investors and among men, and is walloping Obama among NASCAR voters. Joe the Plumber may get his license after all...

Could this be the beginning of the biggest collapse in electoral history? Obama is counting on all those early votes to keep a lead, but if his support collapses, McCain could still take it with a very good day on Tuesday.
