Stephen Colbert, Jimmy Kimmel, and Trevor Noah aren't sure if Biden's #MAMA can beat Trump's #MAGA

On Monday, a new candidate officially entered the 2020 presidential race, "and this time, we have heard his name before," Stephen Colbert said on Tuesday's Late Show. Joe Biden "was already the frontrunner before he declared," but new polls cement his lead.

On Good Morning America, Biden one-upped Trump's trademark slogan with "make American moral again," plus some other stuff. "Move over MAGA," Colbert said. "Because Biden's coming at you with MAMA-MARTTEOWWATDOTCTDOPATOPWD." It looks better on a hat, he demonstrated. "Trump wasted no time taking tweet-shots at Biden," but "going after Biden, it may not be a smart move for Trump," Colbert said, because political advisers warn singling out any top Democrats will just give them oxygen, "and let's be honest, at their ages, both Trump and Biden need all the oxygen they can get."

"Usually when a couple of 70-year-olds are in competition, the winner is whoever yells 'Bingo!' first," Jimmy Kimmel said on Kimmel Live. He thought Biden's "Make America Moral Again" slogan was "a nice sentiment but it is an absolutely terrible hat. It's Joe MAMA."

Biden's first big campaign speech "seemed to be hitting all the right notes — it was connecting with the people — but there was one thing that keen observers noticed," Trevor Noah said on The Daily Show: "The former vice president was a little out of practice when it came to saying words." He played some highlights. "Hudge-fund managers?" Noah asked. "That's why Trump has a huge advantage over every other candidate. If you notice, when he makes a mistake, he doesn't let it trip him up, he just creates a new reality and he plows right through."

"And look, obviously all politicians misspeak sometimes, but because Trump has started a narrative that Biden is old and losing his wits, Biden can't afford any slip-ups," Noah said. He created a Trump "Sleepy Joe Biden" attack ad, and you can watch below.
