Walker needs to appear like the thoughtful, reasoned governor he is known to be. Walker never rammed anything down Wisconsin's throat without fully explaining it and bringing people along.
No, Walker does not breathe fire and get the attention, like Trump does.
But Walker also never apologizes for being a conservative or for implementing conservatism.
Throughout his recall, Walker never retreated from his conservative values or policies.
So, Walker needs to do that here. He was leading the pack and is still in the top tier behind Trump.
Walker should just keep talking reasonably about conservatism and why it is the right policy for the US.
Before long, Trump will be seen as a jester who is annoying and the people will get serious.
