Just my opinion. Walker would be giving a third party opinion. The people who should weigh in is those he lied to. When Mcconnell lies to Walker, then he should have a comment. I don't think serious candidates should make a statement on everything and get into every fight unless it's taken directly to them. They would sound like their pandering for votes.
That was not a small issue in the Senate Sunday....that was huge! And yes the Candidates should have something to say about it....the silence is deafening.
