Anger. And while this may sound overly simplistic, I agree. Libs have been angry since Governor Walker unveiled the reforms which would become Act 10. That was, as I and even liberals have put it, was a "Pearl Harbor" moment to them. It appeared sudden, swift, and in there minds a surprise and unprovoked attack. I've argued this recall is the Right's "Pearl Harbor."
Anger now drives conservatives. Angry that they finally have a Republican who is a true conservative and the left wants to take him away. Angry about the childish, petulant behavior the left has displayed for a year in a half with virtually NO repudication by an elected Democrat. Angry that they are going to the polls, again, for the third time in five months.
Angry at the notion that a temper tantrum might be allowed to deprive them of a full term they expected of Scott Walker. Angry about the Senate recalls, angry about what the left did to David Prosser. The liberal anger was ignited with a single spark. Conservatives have been sitting on theirs for a year and a half and have been waiting, waiting, for an outlet. It comes on Tuesday. Let's see which of the two types of anger turns out to be the primer mover.
