Your analysis of Christie is right on!
Rand Paul thinks we should have a great military primarily geared for defense, that we should quit sending money to ations that hate us, we should help defend our allies, and nation building through war (Iraq) is not the right thing to do. Rand Paul thinks that if we have to go to war, we strike hard, using our power to defeat quickly rather than have a war designed to make defense contractors rich.
Said well!
I don’t think Christie is going anywhere and the GOPe knows it, but they are happy to have a loudmouth slob talk bad about the GOPe’s biggest danger.
