While I agree...are you sure he actually saw her outstretched hand? If he did and refused, that's pretty lame, I agree. I was, however, glad he didn't mention impeachment even once and rose above partisan attacks for nearly his entire speech.
I think one of Talibs tweets sums up today's Democrat party perfectly. She criticized Trump for "bragging about taking food stamps away from millions of people". He didn't take them away, he was bragging about how the good economy 'allowed' them to not need them anymore.
I really don't think today's Dems know the difference. That or they really do WANT as many people dependent on big government as possible to the point of criticizing those that aren't.
