Why wouldn’t he want Romney’s help? He would. He needs all the help he can get right now, as:
1.) He could, in fact, use Romney’s help.
2.) Romney won in the Wisconsin primary. Period. That’s mo.
3.) Romney is the perceived frontrunner/GOP nominee, and has at least some momentum. He could use some of that to help Walker. Walker is a good governor. Walker staying in is a pivotal momement right now for the GOP in 2012.
4.) Again, Romney needs to “Use it (momentum) or lose it.”
Scott Walker is a conservative, Romney is clearly not.
As a Walker supporter, I would be deeply disappointed in him if he asked for Romney’s help.
