With 45 days till anyone votes, anything can happen but its increasingly apparent Jeb Bush is flailing. This weekend Mr. Bush called frontrunner Donald Trump a "jerk", something not usually done by the serious and one time presumptive nominee.
This morning the talking heads are talking about the race as two people. Trump and Cruz, with Chris Christie the dark horse who could emerge in NH.
It's a brawl and anything can happen but as 2015 ends, the message is the old arguments don't hold and "returning to the norm" is not part of the equation. Whether it is in 2016 is an open question.
