The problem with this is that the filibuster ultimately failed to stop Obama. Symbolism is worthless. Wins are the ONLY thing that matters and Walker has produced results.
Unfortunately the US senate is a place where one usually holds office and literally does next to nothing the entire time.
I like Walker, I like his executive experience, but once he is elected, will he capitulate on border security? It seems as if his position is focus grouped, as opposed to a value he holds.
