I can guess why many guys vote for guys like Walker. Excluding the Holy Joes, they are either members of the I've Got Mine school of political thought or, if they're shirtsleeve or struggling white-collar voters, they think that they're bullet-proof and cutting "big government" spending will help them keep more of their money. The fact that privateers will turn things like their pensions and health plans over to private corporations with far less oversight and accountability doesn't seem to make it to their prefrontal cortexes.
I suspect that I'd probably be one of the sorts who'd let someone else do my political thinking for me if it wasn't for the fact that I realized that I'd let people both on the left (Like those marvelous people in the peace community who said that the Khmer Rouge were merely agrarian reformers) and on the right (The ones who said that the old Republic of (South) Vietnam was a democratic regime) lie to me. I learned to put my visceral decision-making over to one side while I searched for facts and information from more trustworthy sources. Over the years I grew willing to let my shibboleths get shattered by inconvenient facts.
Letting one's shibboleths get shattered by inconvenient facts and combing through their wreckage for truth is not a trait of most American "Movement Conservatives."
As women voters who chose Walker, I suppose that either they have a tunnel-vision fixation on abortion, think that their husbands and children will provide for them even in case of injury or illness, or choose to avoid contemplating unpleasant possibilities.
