i'm disappointed that obama released his long form birth certificate for a couple of reasons.
1...it allows trump to make hay out of how he "forced" obama to do something that no one else has done. actually, to be fair, i guess he did. while the birther nonsense is ridiculous to the point of insanity, i'll bet that there are any number of otherwise sane people who don't like obama for whatever reason that are blinded by the celebrity of trump and may confer unto him some type of credibilty that he obviously doesn't deserve. since that was all he was talking about, some people might have begun to think there was something to it. and i'm sure that's what the polls said so obama felt he had to address it.
2...by only focusing on the birther thing, trump was looking like an idiot to most serious republicans. now, it looks like he can force the debate and get things done. by aquiescing, obama made him something that he isn't...a serious contender.
Trump was polling really good so I think he was a serious contender anyways.
You said poll.
