Pledging that "the Mac is back," Sen. John McCain told a hangar full of cheering supporters that he would confound polls and pundits and win tomorrow's election against Sen. Barack Obama.

About 1,500 enthusiastic partisans erupted in applause as the flying version of the Straight Talk Express taxied to a halt at Pittsburgh International Airport. Mr. McCain and his wife, Cindy, emerged, accompanied by an entourage that included former Pennsylvania Gov. Tom Ridge and Sen. Joe Lieberman of Connecticut.

A smiling, ebullient candidate drew a deafening response as he said, "We're going to win this thing. ... Pennsylvania will do it and Pittsburgh will be the important area."

Mr. McCain was back on his plane less than an hour after it landed, heading to another stop in his final, frenetic charge across seven states in his upset quest for the White House. The Arizona senator started his day in Tampa, a pivotal region in a state he must win to have any chance of an Electoral College majority.

From there, he headed to Tennessee -- not a battleground but close enough to attract media attention from two other key states, Virginia and North Carolina.

After his Pittsburgh rally, he headed to planned stops in Indiana, New Mexico and Nevada before opening his Election Day in the small hours of the morning with a last rally in Prescott, Ariz. and finally returning home to Phoenix.

On a stage filled with supporters waving McCain campaign versions of the Terrible Towel, he assailed his Democratic rival on taxes, energy and foreign policy. Seizing words from a January 2008 Obama interview, he portrayed Mr. Obama as someone intent on bankrupting the coal industry. The Democratic campaign has rebutted the contention, arguing that the Republican was taking Mr. Obama's words out of context.

"I believe we should control emission, you know that, but I'm not going to let our coal industry go bankrupt," Mr. McCain said.

Invoking the now famous emblem of his campaign, he sparked "boos," from the crowd as he said, "Sen. Obama told Joe the plumber that he wants to spread the wealth around. ...

"Sen. Obama is running to be redistributionist-in-chief; I'm running to be commander-in-chief,'' he added. "Sen. Obama is running to spread the wealth; I'm running to create more wealth.''
