Fox News’s decision to cap the prime-time debate at 10 candidates was based on five previously-unspecified national polls. This led to weeks of intense speculation over who would be in and who wouldn’t. Recent polls showed a defined tier of a debate eight that appeared to be locked in for the debate. The definite 8 are front-runner Donald Trump along with former Florida Gov. Jeb Bush and Wisconsin Gov. Scott Walker, who have been polling in second or third place nationally, former Arkansas Gov. Mike Huckabee, retired neurosurgeon Ben Carson, Sens. Ted Cruz, Marco Rubio and Rand Paul will round out the top 8. The final 2 will be N.J. Gov. Chris Christie and Ohio’s own Gov. Kasich squeaked in. This group will make for an interesting mix.
