President Trump is already winning the battle for 2020Michael Bloomberg's presidential campaign manager said Monday.

"What we're focusing on is defeating Trump. If you look at the polls, and people can’t focus on this [enough], the general election is in six states, that's it. It's in Wisconsin, Michigan, Pennsylvania, North Carolina, Florida, and Arizona. That’s the whole general election," Kevin Sheekey told CNN's "At This Hour with Kate Bolduan."

"Right now, Donald Trump is winning. He is winning that election," Sheekey continued. "It’s very tough for people who don’t live in New York or California to understand that, but that is what’s happening ... Mike was doing everything he could from the sidelines and he finally decided it wasn’t enough to sit on the sidelines and he needed to do what he could to alter that dynamic."

"Mike is getting in this race because he thinks that Donald Trump is an existential crisis, and he thinks he’s on a path to victory," he said earlier in the interview.

"He’s getting in to alter that dynamic. We’re going to run a campaign against the president. We're going to run a campaign to make Mike the Democratic nominee. We're going to try to bring those together."
