Chaim, I agree with you about Jeb Bush & think he's terrible, but are you sure that the war in Iraq was completely unnecessary? Yes, there weren't weapons of mass destruction & the intelligence turned out to be wrong, but what if the intelligence said that there was a 25% chance that Sadam had them? Where's the cut off point where we should allow the risk of someone who puts people through paper shredders having WMDs?
I don't totally agree with how we fight our wars, but I think Sadam was a threat to us to some serious extent. People say "well, why would he use them against us?" For the same reason Adam Lanza shot a bunch of elementary school kids despite having been 20 years old & having no connection to them (he's nuts). Muslims hate the West, & I don't really trust them with anything.
Also, I don't think Christie was ever a serious candidate. Fox describes him as a "potential 2016 presidential candidate", but he consistently has denied having any interest in running. Fox just hates Ted Cruz & other conservative politicians that might actually run so much that they'll try to rally the base around any RINO candidate (even one with no intention of running). Maybe the establishment could convince him to run, but they've been trying to do that for a while and Christie still doesn't show any interest.
