MESA, Ariz. - Rick Santorum is looking for another upset or two, while Mitt Romney is hoping to keep his leading rival at bay in the run-up to the 20th debate of the race for the Republican presidential nomination.
"I wouldn't be here if I didn't think I could do well," the former Pennsylvania senator told supporters Tuesday after arriving ahead of any of his rivals for pre-debate campaigning in Arizona, a state that has long been assumed safe for Romney.
Both Arizona and Michigan hold primaries on Feb. 28, but until recently, at least, the similarities seemed to end there.
Polls have long shown Romney with a solid lead in Arizona, where all of the 29 delegates at stake are reserved for the top vote-getter in the primary. As a result, neither he, Santorum, Newt Gingrich nor Ron Paul has devoted much time to the state.
Television ads have been scarce, as well. None of the candidates has run commercials, and Restore Our Growth, an outside group that has played a major role in Romney's success so far in the campaign, is the only organization to pay for ads.
In Michigan, by contrast, Romney's lead in public and private surveys began eroding earlier this month when Santorum won upset victories in caucuses in Minnesota and Colorado and a non-binding primary in Missouri on a single night. Now the one-time front-runner campaigns as though he is behind.
Not surprisingly, Romney, Santorum and their allies have poured money into television ads in Michigan -- about $5 million combined, with additions made Tuesday for the race's final week.
While Wednesday's debate is in Arizona, the stakes are heightened because some previous encounters have had an impact far beyond the state where they were held.
Most notably, former Texas Gov. Rick Perry never recovered from his failure to recall the third of three federal agencies he wanted to abolish. His lapse came in a debate in Michigan last November.
And Romney righted his campaign a month ago when he excelled in a pair of Florida debates after losing the South Carolina primary to Gingrich.
Romney campaigned in Michigan on Tuesday, and was pulled into a discussion of social issues by questioners at a town-hall style rally in Shelby Township.
Asked how he would defend religious liberty, he said President Barack Obama's administration has "fought against religion" and sought to substitute a secular agenda for one grounded in faith.
"Unfortunately, possibly because of the people the president hangs around with, and their agenda, their secular agenda -- they have fought against religion," he said.
Obama's campaign seized on the characterization, calling Romney's comments disgraceful and likening them to recent comments by Santorum. The former Pennsylvania senator said recently the president holds a "phony theology," then insisted he wasn't attacking the president's faith, but his environmental views.
