Just because he says a lot of stupid shit that his followers accept as truth doesn't mean he should be restricted from saying that stupid shit. Every time he opens his mouth more people wake up to the realization of how dangerous he is. It's a public service if you think about it.
I get what he's saying, but the history of third parties in the US says this is futile. Then again, the last thing the Democrats need right now is extensive party in-fighting when they should be united.
They wanted to wait a bit before the lying began.
