MCCAIN CONCOCTS IMAGINARY SCHEME…. Once in a while, Sen. John McCain (R-Ariz.) slips so far, I don’t know what he’s saying, and have no idea why he’s saying it.

Here’s the Republican senator talking to Fox News’ Bill O’Reilly about an odious immigration bill advancing in Arizona.

O’REILLY: [W]hat about the racial profiling? You know that’s going to happen has to happen.

MCCAIN: I hope — I would be very sorry that if some of that happens. And I regret it, but I also regret the — really, it’s not just the murder of Robert Krantz. It’s the people whose homes and property are being violated. It’s the drive-by that — the drivers of cars with illegals in it that are intentionally causing accidents on the freeway. Look, our border is not secured. Our citizens are not safe. [emphasis added]

Even for McCain, this is pretty odd. Immigrants who entered the country illegally generally don’t want to bring this kind of attention to themselves. They don’t have any motivation to deliberately cause accidents on freeways.

I have no idea what’s going to happen in McCain’s primary race, but if he loses, it seems very likely that McCain will wake up unemployed in January and realize he did enormous damage to his reputation during his presidential campaign, and then abandoned what was left of his integrity during his re-election campaign.
