I'm not there, so all this is second hand. Sarah Palin isn't there either, and so far this is sort of looking like a smart move.
So far, Don Trump, erstwhile presidential candidate, has addressed the multitudes to the effect that Ron Paul, as a potential presidential candidate is unelectable. Big Deal. It's not like Mr. Trump is particularly electable.
Think about the characteristics you'd like to see in a President. For example, executive experience. Yes, Trump has that, but being a near absolute dictator in an industrial setting is not the same as being a successful big-city mayor or state governor. This is not to say that Bill Gates might not be a passable president, but somehow I just have a hard time seeing it.
