One is forgiveable. A handful is understandable. But Trump has done this too many times for me to just bend over and accept.
Don't forget, Trump endorsed Romney for Senate and we all took that one up the pooper.
Dr Oz is another Romney when there are far better candidates available. Trump is picking the front-runner in hopes he can brag about the power of his endorsements.....which is not the purpose of an endorsement.
I live in PA, and I wouldn't dismiss Oz out of hand because I know statewide elections here are decided by dingbat suburban women. A dope like Oz will play well with that crowd.
