McCain’s 2000 communications director, Dan Schnur makes a great point…
Conventional wisdom correctly suggests that Mr. McCain could benefit from a running mate who adds credibility on economic issues and excites the Republicans’ conservative base. Mr. Romney’s accomplishments in the private sector would be valuable in a discussion of jobs creation and economic growth, but he was attacked relentlessly in his campaign for Senate against Ted Kennedy for the layoffs and downsizing that occurred in companies he had acquired. At a time when voters are worried about their own job security, those same criticisms could pack greater punch this year.
Mr. Romney’s ability to motivate the G.O.P. base is even more of an open question. While Mr. McCain is still trying to shore up his support among conservatives, there’s no evidence that Mr. Romney, who lost those voters to John McCain and Mike Huckabee in the primaries, would help close the sale. Already, several religious conservative leaders have come forward warning that naming Mitt Romney would be counterproductive. Indeed, Mr. McCain can still rally these voters on his own by talking about national security, tax cuts and energy policy, or by scaring them about Barack Obama. But it’s hard to see how Mr. Romney makes that rally any easier.
