It is already happening, but expect it to escalate.

Just a few days ago, National Review reported that Republicans in Iowa are mad at Rubio because of his weak ground game.

Then yesterday came word that Rubio has gone up a point in polling since October and Cruz has gone up 21 points to take the lead from Trump.

Week before last, the Union Leader in New Hampshire was casting doubts on Rubio’s strategy.

Back in October, a number of billionaires were frustrated with Rubio’s campaign and venting. This is in sharp contrast to press reports on Rubio’s clever strategy back in September. Now the press is baffled by Rubio’s strategy.

Rubio is actually keeping his campaign team small and disciplined. They have a plan and they are executing it. But the campaign ground game has been so under the radar as to be undetectable. That has a lot of establishment types starting to get heart palpitations.

Look, it is obvious that Jeb Bush is done for. His Super PAC has taken to attacking Marco Rubio for challenging Obamacare. The Bush effort is no longer serious and we should not be surprised if he is out in time to spend the holidays with his family. That leaves Rubio as the fall back and he seems to be putting no chess pieces in place for victory.

Rubio is the firewall the Establishment has set up. He can unite guys like me who adore him and the Establishment. But if he falters, they will be forced to cut a deal with Ted Cruz to stop Trump. The Establishment would rather Rubio kick it into high gear yesterday to avoid having to cut deals with the man they see as the devil, i.e. Cruz.

Expect the media speculation about Rubio’s strategy to intensify over the next few weeks as the Establishment worries more and more.
