Candidates and bystanders alike have taken shots at the Texas governor over the past week. The 2012 frontrunner, by contrast, has remained quiet.
Since Texas Gov. Rick Perry entered the Republican presidential race, he's given plenty of ammunition to his political opponents - from suggesting that Federal Reserve Board Chairman Ben Bernanke's monetary policies were borderline-treasonous to questioning the science behind climate change.
The scrutiny has followed: Bush adviser Karl Rove called Perry's controversial comments on Ben Bernanke unpresidential. Two of his Republican presidential opponents, from the center and the right, characterized his statements as extreme on national television. Even his successor at the Republican Governors Association, Virginia Gov. Bob McDonnell, called Perry's Bernanke remarks "incendiary," and said he didn't add to the national debate.

Romney has been playing the political equivalent of prevent defense throughout the campaign, avoiding engaging his Republican rivals and keeping his focus on President Obama. And for now, that strategy looks like it will continue, as the Romney campaign hopes Perry will self-destruct and that other opponents will aggressively go after him, allowing Romney to stay above the fray.
"Mitt Romney considers Rick Perry a friend and believes he will add a lot to the discussion during the primary," said Romney spokeswoman Andrea Saul. "But he is going to stay the course and keep his focus on President Obama's failed economic policies. This country needs a president who understands how the economy works and has private-sector experience. That is why Mitt Romney is running."
Romney is unlikely to engage the Texas governor much beyond drawing the contrast between their depthl of experience in the private sector, at least for now. Romney's mission is to present himself as the strongest challenger to Obama. Sniping at Perry doesn't further that goal.
That strategy depends on the media and other presidential candidates doing the dirty work for him. And on this part, he's had some early success. Rick Santorum compared Perry to liberal Rep. John Conyers (D-Mich.) for his red-meat criticism of Bernanke. Jon Huntsman took Perry to task for suggesting that climate change and evolution aren't real. Both are exactly the kind of volatile issues that Romney would rather avoid in a GOP primary.
"In boxing, you don't fight beneath your weight class,'' said Florida lobbyist Brian Ballard, a member of Romney's national leadership team. "Until Perry has been out there a couple of months and shown that he is a legitimate rival ... I don't think we'll engage him much.'' Romney's silent treatment largely hinges on Perry. Even as Perry has taken shaken up the GOP field, his controversial remarks have stirred fears among many Republicans that the governor could give a vulnerable Obama an opening in the general election. Rep. Paul Ryan (R-Wis.), New Jersey Gov. Chris Christie and Sarah Palin have reemerged as long-shot possibilities to enter the race, more a sign of establishment dissatisfaction with the field than of their seriousness of mounting a late run. The ability of the nominee to defeat Obama is high on the minds of many Republican voters, said Alex Castellanos, an unaffiliated GOP strategist who worked with Romney in 2008.
