The thing to remember is that we can’t really trust any of THEM because only GOD knows what is in their hearts and what they will do for money and to save their own asses behind closed doors. The thing with Trump is he has a lot to lose because of all his holdings if America goes away so let him fight for it for now. Let him poke the media, Democrats and dweebs stinking up our party. We always have Cruz. The lesser of all the evils can still be an evil.
No we can't, however we have been given wisdom to make wise choices based on past actions/stands. When someone takes certain positions right before running for an election that are opposite to the positions they used to hold, then you have to wonder about that.
