The serious questions should start with the “wall” the Clinton cabal created barring communications between the FBI and CIA; the ignored opportunities to take custody of bin Laden, and Bubba’s abject failure to substantively reduce the threat from al-Qaeda after the embassy bombings.
But Trump will never ask those questions .. those that may embarrass Clinton.
If he goes head to head with Hillary in the general, that is going to come up, and he would make mincemeat out of her. She’s going to get schooled on what matters.
Right now he isn’t vying with Democrats. He is vying with Republicans. The Lord makes everything beautiful in its time.
