many questions were asked at today's press conference. none of which unfortunately could be heard on anyone's microphones so it made the press conference hard to follow on tv. but the basic question here is if you're donald trump why change now? if you pitched your team all the way to the world series by throwing your amazing knuckle ball that nobody could hit, why stop doing that and instead start throwing fastballs just because everybody else does? an unnamed adviser to mr. trump's campaign tried to explain the logic of signing the political pledge saying he was changing course on running as a third party candidate because he wants to inoculate him of supporting liberal candidates and policies. he doesn't want to be criticized for it at the next debate. honestly, and with all respect that makes no sense.
