Many Republicans feel the primary process has been a critical pressure-test for Romney's campaign skills, resulting in a more honed and prepared candidate.
"He has weathered incredible attacks and remained largely disciplined," said one GOP Insider. "Much more of this and he'll be weakened but for now, it's good practice for November."
"The primaries gave Romney the field-testing he needed and helped him build credibility with skeptics," agreed another Republican.
"It's the first time he's won outside of Massachusetts," pointed out a third. "He needed this. Most candidates improve through the process."
Some Democrats agreed. "He has gotten better in debates, more disciplined in his messaging and more comfortable as a candidate," said one. "Yes, he was exposed for being a flip-flopper, but that was going to happen anyway."
Republican strategists also felt Romney would ultimately benefit from the early airing of potent attacks likely to re-emerge in the general election, especially those related to Romney's time at private-equity firm Bain Capital.
"His wealth and the Bain bomb were going to become an issue regardless," reasoned one Republican Insider. "The primary campaign has made him a better candidate, better on his feet."
"It's much better to deal with the Bain Capital issues now, instead of later when Obama's billion-dollar campaign kicks in," said another.
"A primary almost always makes the eventual nominee stronger in terms of overall capacity as a candidate," echoed a Democratic Insider. "And anything that has come out now, such as the Bain attack, was going to come out."
Many Democratic Insiders, however, disagreed on that point, claiming that Romney's Republican opponents have set in motion negative messaging on Romney that will reinforce Democratic arguments in the general election.
"A ten-month discussion on his job-killing record at Bain is better than a three-month discussion," said one Democrat.
"The questions raised about Romney's lack of core principles and political opportunism are invaluable in forging his image with the American electorate," said another.
"His opponents have saved Obama countless hours and dollars by framing a line of attack," agreed a third.
A few Republicans expressed the same concern.
"We made Bain and 'vulture capitalism' an even more legitimate line of attack among non-Republicans," lamented one GOP Insider. "How can that help?"
Democratic Insiders also argued that Romney's persona is not well-suited to extended exposure to the American electorate.
"His disconnect from the lives of the majority of Americans is manifesting itself more every day," said one Democratic strategist.
Explained another: "Romney does not wear well. The more time you are exposed to him, the less you want to have a beer with him."
Still, at least one Republican looked to science to explain his optimism that Romney's roller-coaster ride in the primaries would ultimately benefit him.
"It's called hormesis: exposure to a toxin or stressor that makes you stronger. Thanks, Newt!"
