1. Calls illegal immigration an "act of love"
I don't know... probably the same thing his brother was thinking that won him the White House. Check out the percentage of the Hispanic vote McCain and Romney picked up compared to W Bush.
Maybe he actually has self respect and doesn't want to be a flip flopper. Also the Republican big business establishment is appalled with the product coming out of schools. Remember common core was designed by governors in conjuction with the private sector. It wasn't something cooked up in Washington. Bush is just trying to be consistent. Bush and his kind asked for common core. They designed it. They championed it. It's actually the Republicans who are running away from it now who should be asked what they are thinking.
