A recent Pew Research Center survey supports my impression. It has 20 percent of white Clinton voters saying that if their candidate does not get the Democratic nomination, they might vote for McCain. Older, lower-income and less-educated Democrats also indicated some willingness to support McCain if Obama is the candidate. These are your Reagan Democrats -- blue-collar voters who responded to the broad appeal of Ronald Reagan.
Gilbert Ray, a Democrat from Fayetteville, N.C., describes this inner conflict as follows: "There's a lot that he (McCain) believes in that I disagree with, but unfortunately Sen. Obama doesn't appear to me to have any answers to anything."
"I was young once, and I remember not delving very deep into the candidates' qualifications," he went on. "But I'm 60 now, and I'm very worried about the country, especially after eight years of G.W. Bush and his insane non-government."
This year each party has a mold-breaker out front. McCain virtually has the nomination, and Obama is neck and neck with Clinton. Independents like both McCain and Obama. As this relentless campaign wears on, however, the two candidates will seem less and less fresh and original.
