Obama Visits 'Toot' While Campaign Rolls On

The campaign says that since Labor Day it has contacted 1½ million voters in Ohio, a battleground state that went for President Bush twice.

Michelle Obama also held rallies in Akron and in Columbus, Ohio, where she stressed her husband's family background and his community organizing as signs that he understands the problems of everyday people.

Surrogates in Full Force

While Michelle Obama made her stump speech, Obama's surrogates were out in full force, with running mate Sen. Joe Biden focusing on West Virginia and Sen. Hillary Clinton hitting Pennsylvania.

Biden attacked the Republican campaign for negative campaigning, particularly for using robocalls against Obama.

"We have to end this politics of division and divisiveness," Biden said. "End the scurrilous phone calls that are being paid for by the McCain campaign questioning Barack Obama's patriotism, questioning his character. Enough is enough!"

Hillary Clinton was in Pittsburgh. Pennsylvania is one of the few states John Kerry won that Obama is defending, although he leads in polls there. Clinton voiced strong support for her former foe.

"I have been campaigning so hard for Barack Obama I lost my voice somewhere between Orlando, Fla., and Hibbing, Minn. If you find it send it to me OK?" Clinton said.

While Obama took personal family time today, his campaign remained on offense. After spending most of the day visiting with his ailing grandmother today, he will board a plane for Nevada. After that, he will make stops in New Mexico, Colorado and Ohio -- all states won by President Bush in 2004 that are up for grabs this year.
