BYRON YORK: 12 keys to the GOP presidential race right now.

1. The candidates who have run before — Mitt Romney, Mike Huckabee, Rick Santorum — all think they can get their teams back together for another race. They can’t. Each man has been in touch with staff and supporters from 2008 and 2012, with the assumption that the people who were willing to work for them back then will do so again in 2016. But the world has changed; issues have changed and new candidates have emerged. Moderates who backed Romney now have Jeb Bush and Chris Christie to consider, while conservatives who backed Huckabee and Santorum have Ted Cruz and Ben Carson. Even if the veterans run again, they won’t be able to recreate what they had before. They’ll have to do something different.

York has 11 more, and they’re all worth reading, but let me reiterate my belief that what the GOP needs is fresh blood, not people who have been running for President since the iPhone was new.
