He’s actually in.

This probably hurts LeMieux and McCallister the most. LeMieux because he will no longer have the “moderate” tag to himself. McCallister because he was never really doing well because people liked him, but just because they weren’t sold on Hasner and LeMieux – and now Mack will be the new shiny object for folks to look at.

The question now becomes whether Mack will be able to pull in the DC money that was flowing more to LeMieux and how much will state based interests put into independent expenditures on Hasner’s behalf (the corollary being whether Mack can raise enough to deal with those IEs).

Also, how much heat will he get for being married to a California congresswoman? It makes for a fine argument that he’s not really as deeply attached to Florida as he ought to be – presumably he’s spending not insignificant time in her Palm Spring district, as well spending a lot of time keeping house together in Washington. I don’t pretend to know the answers, but someone’s going to make hay out of this.
