On election eve (Monday) McCain will make a quick stop in Roswell, NM around 3pm.
The presidential hopeful made a cameo appearance at the beginning of the show, with Tina Fey reprising her memorable impersonation of McCain's running mate, Alaska Gov. Sarah Palin.
McCain, who is trailing Democrat Barack Obama in most battleground state polls, also appeared during the show's "Weekend Update" newscast to announce he would pursue a new campaign strategy in the closing days of the campaign.
"I thought I might try a strategy called the reverse maverick. That's where I'd do whatever anybody tells me," McCain said.
And if that didn't work, "I'd go to the double maverick. I'd just go totally berserk and freak everybody out," the Arizona senator quipped.
Earlier in the show, McCain and Fey, portraying Palin, said they couldn't afford a half-hour campaign commercial on network television like Democrat Barack Obama aired earlier this week. They said they'd sell campaign products on the QVC shopping channel instead.
Among other things, McCain advertised a set of knives to cut through pork in Washington. His wife, Cindy McCain, briefly appeared to advertise "McCain Fine-Gold" jewelry, a play on the campaign finance law McCain authored with Wisconsin Democratic Sen. Russ Feingold.
Fey, as Palin, advertised a set of "Joe" dolls commemorating Joe the Plumber, Joe Six Pack and her Democratic rival, Joe Biden.
The pretend Palin also pulled out T-shirts saying "Palin 2012" and said she wouldn't be returning to Alaska after the election.
"I'm either running in four years or I'm going to be a white Oprah," she said.
