On Monday’s “Morning Joe” on MSNBC, Politico White House correspondent and Playbook editor Mike Allen said he expects Gov. Scott Walker (R-WI), a potential candidate for the 2016 Republican presidential nomination, to go “nuclear” against another potential competitor in former Gov. Jeb Bush (R-FL).

“He’s going to be much tougher on Jeb Bush than anyone else, most especially Marco Rubio,” Allen explained. “We have a piece up on Politico looking at the one race that Scott Walker lost. He famously won 11 races as a Republican in the swing state of Wisconsin. But the one that he lost, in ’06, you remember this – he was going for governor against Congressman Mark Green … and he started late. Green had locked up the establishment and as Milwaukee County executive, got no traction.”

“So what did he learn from that?” he continued. “Two things – one is you have to go big. We see Scott Walker hiring up staff. His competitors think more staff than he needs, trying to push himself into the top tier. And second, you don’t take anything for granted. Go very tough and so we know that the Walker superpac is going to go nuclear against Jeb Bush, whereas Marco he’s going to be much more cautious.”
