Maybe his charity wants to buy Time Warner.
(Edit: people are now going around downvoting my other comments because of this one. Good work guys, Emperor Trump has noticed your efforts!)
1) He lies every time he opens his mouth, so I wouldn't take what he says at a rally (or a hot mic) at face value.
2) They won't consult him for his opinions on mergers and acquisitions when he's serving his prison sentence for sexual assault.
Finally, if past elections are any indication, I would not recommend voting for someone based on one issue. Campaign promises are more difficult to implement than candidates imagine.
If you like Trump, by all means vote for him, but don't vote for him over AT&T and Time Warner.
Oh, the candidates know it damn well. But they know the electorate doesn't know it. So they lie their asses off because it's how you win when all the other candidates are lying their asses off.
Bernie supporters actually believed he could usher in universal healthcare, free college, etc. Trump supporters think he's going to build a giant wall. Johnson supporters think they're going to get legalized weed in the entire US. As if the presidency was a monarchy and the legislative and judicial branches didn't exist. (Clinton supporters ... well they're just terrified of Trump winning.)
We don't have the candidates we need, but we sure have the candidates we deserve.
A presidential appointment is very important. They nominate Supreme Court justices (although the new rule for the senate is apparently refusing to vote on/approve of nominees if the president doesn't belong to your party.) They have veto power over laws, and can force a supermajority. They do have some level of control over military actions (not enough to unilaterally start World War 3, but still.)
But they do not have absolute control. If Bernie wants universal healthcare, he'd have to get congress to pass it. The same congress that barely passed the insurance industry's dream legislation created by the Republican party in the first place. You think that congress is going to pass single payer? Or free college education? Keep dreaming. Sure, if we elected 60 senators like Bernie Sanders, we might be able to do something amazing. But Bernie alone? Not enough. Obama couldn't even shut down Guantanamo Bay.
Don't get me wrong, I'd have been elated for Bernie to have won the election. It was obvious in 2008 with Obama's reversal on marriage equality that he was just another career politician. Clinton is far worse than even Obama. Bernie was the first candidate I actually believed meant what he was saying. He had an entire lifetime of advocating for the change he spoke of. But you're hopelessly naive if you think he could have actually brought about the things he wanted.
The group who back the archetype of incivility are smashing a system that was meant to facilitate reasoned discourse? What a surprise.
Perhaps the recent flood of such behavior is related to funding a reversal of diversity and calling that act of reversal "tolerating diversity".
