What does this mean?

I saw this gas-guzzling SUV parked alongside Grand Ave as you approach Shiloh going west. It seemed like an in-your-face way of attracting the attention of the environmental wackos. I didn't immediately see the subtitle "Conservative Republican." But when I got a little closer I did note this modification of an ordinary Republican candidate, perhaps a little redundant, but then I am an old fuddy-duddy. Since then I've noticed a few other signs on the roadside and quite a few radio ads with the words "conservative" and "common sense" mentioned. The name Kennedy might get confused with another Kennedy who has not yet made the jump from relatively conservative local Democrat to the usual far out leftist Democrat suitable only for serving in Congress. But with the other signs and ads I think this might be a harbinger of future events, e.g. the House of Representatives moving decidedly to the right and perhaps the Senate finally getting rid of a few seditious old farts on the Left. You know who they are. This should be interesting.
