The questions were definitely chosen to favor Clinton. The question about the birth certificate for example could only hurt Trump and was a gimmee for Clinton. The birth certificate is not even a campaign issue.
Actually Trump missed an opportunity with the Birth Certificate. He should have turned it around and asked why he should apologize for the president taking over two years to do what every 8 year old must do when signing up for little league. Then turn it another 90 degrees and point out that this is what is wrong with race relations, when something that should be a simple taking care of business action gets shrouded in racial overtones.
Trump is a good counter puncher, but he missed many opportunities last night.
