How bad does John McCain want to win his Senate primary? Well, he’s now got a get-tough-on-the-border commercial that completely ignores his previous positions, statements, and attitudes and that would probably bring tears of joy to Tom Tancredo. At this rate, next week he’ll denounce McCain-Feingold campaign finance reform as an unconstitutional restriction on the First Amendment.Gehraghty also reminds us to keep things in perspective - primary opponent J.D. Hayworth is keen on painting McCain as being as pro-immigration as possible. Even if McCain was a little lax on the issue, he's going to seem even more so during a heated campaign that has been almost exclusively focused on that issue.
