This is exactly what Trump does, just without nafarious intent.
I absolutely think Joe is slipping mentally. He's always been a bumbler of words, this is different. Someone really should tell him to call it a day. This has 2016 2.0 written ALL over it.
I don't know that it's exactly what The Clown (who seems more aware of what he's saying) does. I think Biden is old and overwhelmed and tired, and a wee bit imperious as a former VP, so he's making mistakes. I don't know that I expected more from him. To me, he was the conservative, established, white guy they put on the ticket to appease people who were uncomfortable with Obama. There are a large number of people who want to return to "glory days" and believe Biden can return them to that, when in actuality we need something different. So, yeah, he could lose us the election.
