GOP race: the field may NOT be closed

Rhodes Cook, of the polling company Rasmussen, argues that it's not too late for another GOP candidate to enter the field:

Conventional wisdom is that the Republican presidential field is set, and that it is much too late for a new candidate to enter the race.

In years past, that would be absolutely correct. Over the last few decades, dozens of primaries and caucuses have been shoe-horned into the opening weeks of the election year, with the tendency on the Republican side for the front-running candidate to score a quick knockout.

But next year, the arrangement of the primary calendar is much different. It is less condensed at the front, much more loaded with events at the back, with the prospect of a viable, late-starting candidate quite real.
