Romney to stump with McCain today

Mitt Romney is planning to make his first campaign appearances today with John McCain since endorsing the presumptive Republican nominee.

The former Massachusetts governor plans to help McCain raise money at an event in Salt Lake City, then go to another fund-raiser in Denver, the Associated Press is reporting. McCain is on a weeklong swing to replenish his campaign offers, and Romney is popular in Utah and Colorado, states with large numbers of fellow Mormons.

Asked about the possibility, Romney has already said he would be "honored" if McCain picked him as his running mate. But at several points during the Republican primary race, such joint appearances seemed far-fetched.

Before the New Hampshire primary, Romney suggested that McCain was too old and decrepit to change Washington, and McCain compared Romney to a pig wallowing in the campaign muck. Before the Florida primary, Romney accused McCain of lying about his stand on Iraq and of not knowing much about the economy. They had several heated exchanges during a debate before Super Tuesday.
