McCain Yard Signs

I'm wondering what other people think here. I need opinions.

As I wander around my neighborhood (dragged around the neighborhood by my dog would be technically more accurate), I'm seeing more and more "McCain/Palin", "Families for McCain" and the excruciatingly inexplicable "Women for McCain" yard signs appear in the lawns of ostensibly working-class families. There are a few "Obama" and "Obama/Biden" signs around as well, but not nearly as many as the collective McCain ones.

I know I live in a red city (Waukesha) in a red county (Waukesha), in a mercifully blue state (Wisconsin) but really. WTF???? Women for McCain? Seriously? Women? For McCain? I want to knock on their doors, shake them (vigorously) and ask

"What the hell is wrong with you? McCain? The serial liar? The guy who never met a deregulation bill he didn't love? The guy who votes against equal pay, increases in minimum wage and wants your kids to die for a useless war in Iraq? He's really got your back? John McCain?"

I think I know the answer before I even try this tactic. These are the so-called "values voters." The voters I lovingly refer to as the "counter-interest voters". The ones who are blinded by a smoke screen of conservative religious propaganda and consistenly vote against their (and their family's) interests.

So my question to you all is, is it worth trying to engage these folks in polite dialogue? Should I ask them the simple "McCain? Really? Why McCain? What does he bring to your table?" You know, polite political discourse. Has anyone done this in their neighborhoods? Any Obama converts?
