According to reporting by The Boston Globe, there are two issues in play. First, back in 2002, when Romney was rescuing the Salt Lake City Olympic games from chaos, Perry wanted the Boy Scouts of America to be named the official volunteers of the games. Romney said no because most scouts are under 18, the minimum age to work at the Olympics.

Perry, however, thought there was a gay component to Romney's decision, since the Boy Scouts do not accept declared homosexuals as scoutmasters. Romney denied that.

Then in 2006, Romney traveled to Texas as the chairman of the Republican Governors Association. He met with Perry, who was furious that Romney had hired a man named Alex Castellanos as an adviser. It seems that Castellanos was also advising Carole Keeton Strayhorn, who was running against Perry for governor. It was a chilly meeting.

On paper, those incidents look small, and they are. But now Romney and Perry find themselves in a high-noon situation, and there will be a showdown, most likely in the form of a debate. At the end of the primary season, only one will be standing tall.

I say that because there is not much chance that Michele Bachmann, currently running third in the polls, will gain enough traction to threaten the governors. The congresswoman is waging an energetic campaign, but big-money Republicans are looking for "gravitas" this time around, not ideology. Those running the GOP well understand that economics will decide the next presidential election.

Both Romney and Perry are well positioned in the economic arena. While governor of Massachusetts, a liberal bastion, state bonds received an upgrade by Standard and Poor's, the credit rating agency that just downgraded the USA.

Perry's economic story is solid, as well. Texas leads the league in job creation in the teeth of a stubborn recession, and tort reform has attracted major medical concerns and personnel to the state. So, on balance, both governors match up well against Obama in the area of economics.

Perry is counting on his conservative credibility to hold his poll lead over Romney, who is suspect in some rightwing precincts because of the Massachusetts health care law. You may remember that Obama gave Romney credit for passing the law, which, of course, was like putting a nail in the governor's shoe.

The Romney-Perry match-up should be interesting, especially if it gets vicious. Both men are capable of slinging some mud. And with the hair situations they both have, that could get messy.
