More than 20 Democratic presidential candidates descended on Clear Lake, Iowa, on Friday evening for the state party’s annual Wing Ding dinner as they blitz the critical early voting state this weekend, making their pitch to voters.

Candidates continued to go after the president's rhetoric and behavior on Friday night, with Biden accusing him of exercising "a political strategy of hate, racism and division."

"Donald Trump doesn't get it. He truly doesn't understand what we're all about," said Biden, who sat in the audience while his fellow Democratic rivals spoke before delivering the final speech of the night.

"Take it back now. This is America," Biden yelled. "Take it back."

Though the state’s caucus is not until Feb. 3, the Iowa State Fair and its peripheral events are longtime staples for presidential candidates as they seek to jockey in what this cycle has become one of the most crowded primary fields in modern history.

While Democrats seeking to take on Trump next year kept the president in focus, they also touted their own policies Friday night, with Warren highlighting her proposed “wealth tax” on the ultra-wealthy to help pay for a bevy of programs, including universal child care and eliminating student debt.

“We’ve had enough of an America where the government works better and better and better for a thinner and thinner slice at the top. 2020 is our chance, we can make this government work for all of America,” she said. “Let’s do this, Democrats.”
