The fact you don't is the problem.
First off, who cares.
Second, you now can't endorse someone if they have any single thing you find objectionable?
Frankly, I don't know whether Barry was born in the USA, the fact he won't produce a genuie BC to end this makes him look like a douche, but its not something i care about.
So now before you say I like this guy's political ideas you have to make sure he never said or did anything that some butthole didn't like or be called a crank?
Get serious, what you are doing is called 'politics as usual' and we all have damn well had enough of it.
Who cares what the **** this guy called barry, is he able to do the job he's being endorsed to do?
THAT is what matters.
I don't consider believing the President of the United States to be not born in this country and comparing him to Osama Bin Laden to be a minor matter. If it were a matter of political differences, this would be irrelevant. It's the same deal as believing that Bush and the Government were behind 9/11 and that there are FEMA death camps.
And well you're not about to go and support a neo-nazi for office are you? You could completely agree with his views, but are you going to vote for him with that knowledge in mind? I don't know about you, but I'm not going to. Character is a important part of the candidate. Coakley looking down upon shaking hands with her voters lost her votes big time and showed she had a lack of character.
