Exclusive: Harris adviser warns of "all-powerful" Trump if he wins

• But Plouffe, who served as former President Obama's 2008 campaign manager, told Axios' Mike Allen that democracy will be part of the speeches this week.

What he's saying: "Freedom really does cover a lot of important areas to the American electorate, and of course the flip side is Donald Trump is a threat to all of those things," Plouffe said.

• "When somebody basically says they want to be a dictator on day one ... that gives you a pretty good sense of how that person wants to act as president."
• Plouffe added that Project 2025 is about "removing the guardrails, so Donald Trump can be an all-powerful, all-encompassing figure in our lives and I think that's going to be a very important part of the election."

Zoom out: Democrats have repeatedly tried to tie Trump to Project 2025, the conservative plan that backs a dramatic expansion of presidential power.

• Trump has tried to distance himself from the conservative vision, which is not an official Trump campaign platform but was created by several of his allies.
