The media helps Trump spread lies when they broadcast his speeches. Sure, they correct some of it after the fact but the damage has already been done.
They won’t do it but I think the networks should show Trump’s speeches on a tape delay like they use to make sure curses are not broadcast. They could edit out the lies and only broadcast the parts that were true. Of course, that would make for some very short Trump speeches.
Trump has no incentive not to lie since the networks will spread his lies. If they stopped broadcasting his lies, they would give him a reason to tell the truth – if he’s capable of it. Sad!
