The last scheduled debate in the Republican presidential primary campaign begins at 7 PM CST in Arizona.

The candidates have shown great intellect and courage throughout the campaign, and tonight should be no exception. The main issue has boiled down to which candidate is the farthest right. Most of the candidates concede that their opponents are really, really conservative, but they all claim to be the only true triple-really conservative. Mitt Romney asserted last week that he was a “severely conservative” governor in Massachusetts, and Ron Paul just released a commercial calling Rick Santorum a “fake” conservative. If you’ve heard Santorum’s views on any of the issues, you’d have to say he’s faking it pretty well. Speaking of authenticity, the Paul commercial also uses the words “dude” and “groovy”—and aren’t those the first words that come to mind when you think of Ron Paul?
