How worried is Walker?

Worried enough about Mark Neumann to send this trash job to Republican mailboxes this weekend.  Neumann as Pelosi seems a little over the top.  Will Neumann finally fight back, or continue to play rope-a-dope?

Afterthought:  What Walker may be worried about is not winning the primary,but meeting expectations.  His people have been saying for awhile their goal is 60% in the primary, which means they probably expect to win 2 to 1.  A squeaker, or even something less than the 60-40 they're predicting,  would be a major setback.  He doesn't just want to beat Neumann, he needs to crush him.

UPDATE:  Walker will begin running a television spot on Tuesday with the same message, linking Neumann and Pelosi.  (By the way, Tom Barrett was in Congress then, too, and voted against the bill.)
