Political blogs are lighting up over GOP presidential candidate Ron Paul walking out of an interview with CNN's Gloria Borger, who was pressing for answers about newsletters published under Paul's name in 1980s and '90s.

See The Week's take on it here.

Apparently, the newsletters contained comments about minorities and others that could, without much effort, be taken as bigoted or at least astoundingly ignorant.

Paul first tries to brush the questions off. It all happened long ago, he's talked about it all before, he didn't write them, he didn't read them and he has disavowed them.

Then Paul does what Paul does. He claims he's being picked on because he's the only virtuous man in Gomorrah and stalks off.

Given that the newsletters offered opinions about people Paul would be governing were he to be elected, questions about them are perfectly legitimate.

Even if they weren't, he needs to face the heat, not run from it, if he wants to be taken seriously.

Few political candidates have escaped questions about things that happened in the past, or never happened at all.

See Obama's birth certificate and religion, Herman Cain's alleged philandering, W. Bush's National Guard service, et. al., Bill Clinton's pot smoking, John Kerry's Vietnam service, etc., etc., etc.
