Democratic lawmakers harbored deep concerns about Joe Biden's presence on the presidential ticket, fearing it could have disastrous consequences for their party's down-ballot races. They were particularly worried about the potential impact on the Senate, where a Biden loss could cost them control of the chamber. Even if all their incumbent senators won, a 50-50 split would hand control of the Senate to the president's party, which in this case would be the Republicans. This scenario would significantly hinder the Democrats' ability to advance their legislative agenda and confirm presidential appointments.

Furthermore, House Democrats were deeply concerned about the potential for a depressed base and historically low voter turnout, especially in swing districts where elections are often decided by narrow margins. They feared that a Biden loss would discourage their base from voting, leading to a significant decline in turnout that could cost them control of the House. This would further exacerbate their challenges in enacting their legislative priorities and could have far-reaching consequences for the party's future.

The lawmakers' concerns were rooted in a deep understanding of the political landscape and the challenges facing their party. They recognized that a Biden loss would not only be a setback for the Democratic Party but could also have significant implications for the country as a whole. They were determined to do everything in their power to prevent such an outcome and ensure the success of their party's candidates in the upcoming elections.
