Bernie Sanders says he’ll be better for down-ballot candidates than Hillary Clinton.

Appearing on Meet the Press this morning, Sanders took issue with the conventional wisdom that Democrats running for Congress would prefer Clinton at the top of the ticket. “Hillary Clinton will be the problem,” Sanders told Chuck Todd. “Because I think our campaign is the campaign that is generating excitement and energy that will result in a high voter turnout. Republicans win when voter turnout is low. Democrats win when voter turnout is high.”

Todd noted that House Minority Leader Nancy Pelosi had warned that Sanders’s proposal to raise taxes to pay for his single-payer health care plan would turn off voters in the general election. As Sanders makes his final push in Iowa, he’ll be hoping that voters don’t buy Pelosi’s argument.
