There is a flaw of character that encourages Newt to not honor his obligations to his campaign workers and his creditors. It is the same flaw that caused Newt to sit on a love seat with Nancy Pelosi and make TV commercials for Al Gore's global warming scam, to work with Sharpton to get taxpayer money for black racists and con men and to “lobby for” more money for Freddie Mac at a time when it was recklessly facilitating the stealing taxpayer money.
I don't think Newt is a principled conservative. I think he is an opportunist who realized sounding like a conservative would help his campaign.
I admire many of the things Newt did in the 1990’s when he was Speaker of the House. But today he is just another Washington insider who has learned how to play the system.
