Why isn't Trump qualified? He's old enough and he's a US citizen. He's not a politician and that is a big plus. He's as much of a Republican as you or any other party member. No, I'm not a Republican. I'm a registered Independent who has never voted for a democrat. So does that somehow disqualify me from commenting?
He's not a Republican. He's a New York liberal.
His positions on issues like socialized health care, Planned Parenthood and others exposes him as a NYC liberal which make him unqualified to lead a party whose general platform positions have traditionally opposed socialized health care and Planned Parenthood.
He lacks a clear set of values, which is why he does things like fluctuating multiple times on a position. We saw that last week with his lack of a position on abortion.
He lacks the most basic understanding of how our government is structured, something that became clearly evident when he promised to select judges to the Supreme Court who would "look into" Hillary Clinton's many questionable affairs.
He is vulgar and viciously short-tempered, and having grown up coddled and served to, he believes himself the repository of all wisdom. Watching him speak, his inability to string a proper paragraph together that makes any sense to any question that requires a measure of understanding of the issues fully exposed, would be comical, if not for the fact that he's running for POTUS
He is not only unqualified for the office, but unworthy of it.
I was right, you're not a Republican. Well, I am, and I am discussing the qualifications of the man who wants to represent ME in the coming elections
You, on the other hand, are not a Republican.
You willingly gave up your voice in the process, so you now need to own the consequences of your decision and get out of the way of Republicans doing Republican business.
