Here are the names of all the Republicans that I hear are considering a run. Some are widely known, others might come as a bit of a surprise:
Ted Cruz
Rand Paul
Mitt Romney
Chris Christie
Mike Pence
Scott Walker
Jeb Bush
Bobby Jindal
Rick Santorum
John Bolton
Rick Perry
Paul Ryan
John Kasich
Mike Huckabee
Did I miss anyone? Let me know.
This is a HUGE potential field, and it will coalesce into the establishment versus the conservatives. It will require some sorting out, but I am told the GOP learned its lessons from 2012 that nineteen debates is a horrible idea.
