It doesn't matter what he "wants"... there is absolutely no evidence that he would get anything from Cruz on those issues - and Cruz actually has a record, as opposed to Trump.. But it appears that trump is prepared to give the LGBT crowd a lot of support, and they don't even have to give him money to get him to do it - he actually seems to believe in it. So why are you so offended at Cruz, who has never supported the LGBT agenda, but not offended at Trump, who does?
Good grief get a grip, all are not what is best on social and fiscal matters so stop being so damn defensive over one guy, your guy.
