“The top fundraiser in the Democratic presidential field was hospitalized with a heart attack, the longtime polling leader and his son sit at the center of an impeachment inquiry, and the one candidate with clear momentum faces persistent doubts among some party leaders that she is too liberal to win the general election,” the Washington Post reports.

“With breathtaking speed, the events of the past two weeks have created huge uncertainty for the candidates who have dominated the Democratic nomination race, shaking a party desperate to defeat President Trump next year and deeply fearful of any misstep that risks reelecting a president many Democrats see as dangerously unfit for office.”

“Leading donors for Joe Biden convened this weekend for their first donor retreat since he announced his candidacy and struck a determined posture as Mr. Biden’s campaign found itself under assault from President Trump, losing its clear front-runner status and lapped in the money chase by multiple Democratic rivals, most notably Senator Elizabeth Warren,” the New York Times reports.

“Over cocktails on Friday evening and a Saturday spent in a drab hotel conference room, Mr. Biden’s top financiers and fund-raisers received strategy briefings and PowerPoint presentations, and plotted the path forward for the former vice president, who suddenly found himself in fourth place in the money chase.”

President Trump accused Democrats of “interfering” with the 2020 presidential election and the “continuing to interfere” with the 2016 election.

New York Times: “For more than a week, President Trump had been hurling unfounded accusations about Mr. Biden, his son Hunter and their dealings in Ukraine. Mr. Biden and his advisers debated whether to mount a fierce counterattack or to stick to a set of policy arguments he had been planning to roll out. Bad news loomed in the background: Mr. Biden’s poll numbers had already grown wobbly, his fund-raising was uneven, and cable news was flashing chyrons by the hour showing Mr. Trump’s wild claims.”

“Mr. Biden himself was equivocating: He wanted to defend and protect his son, but he also believed the president was baiting him into a dirty fight. And as a lifelong adherent to congressional tradition, Mr. Biden was wary of acting hastily as an impeachment inquiry was getting underway.”
