Punchlines: Presidential race has disasters, hacks and interview setbacks

So, which candidate's campaign should be taken least seriously?

That's a question that Seth Meyers tackled during Thursday night's late-night lineup after Donald Trump stated that Democratic presidential nominee Hillary Clinton has the most "unserious" campaign in U.S. history. Really? Meyers shows how that accusation can't possibly be true in today's Punchlines, above. Meyers also tells us how Trump's inappropriate comments about women surface yet again.

And speaking of least serious, is the world supposed to take Libertarian candidate Gary Johnson seriously after he couldn't name one world leader he admired? It's not that he doesn't admire any, it's that he couldn't remember their names during a town hall-style discussion with Chris Matthews, host of Hardball on MSNBC. Will this be a setback for Johnson's campaign? Can it get any worse for the candidate at this point?

And what was the biggest disaster of Monday's presidential debate? Watch today's Punchlines to find out.
