Of course, “they” (Liberals) are very worried about Walker. His record in Wisconsin makes that inevitable. We may judge how viable Walker’s candidacy is by the volume of Liberal lunacy and hysteria hurled in his direction. Personally, I expect the volume to become deafening. Liberals are devolving to their usual tactic; ignore the issue (s), attack the person.
These silly people. They really do believe that if you can kill the messenger, then you don't have to read the message. Let alone engage and respond to it in a logical, rational way.
Oh, how they try to cheat!!! But for all their machinations, Reality is still what it IS: It does not yield to silly people.
