I guess this will be Rick's Florida. This thing is over.
It was over from the beginning (from 2008) in a way.
But Rick will keep on fighting.
Remember when Huck left the race ? When it was absolutely sure than, numerically, The Mac would gain more than 50% of delegates. Whereas McCain won on Super Tuesday and Huck wouldn't be able to outnumber him, he stayed in the race for many, many weeks.
As Louisiana is on Saturday, Rick will have some favourable media buzz just 4 days later. Why not stay in the race ?
