Biden vows to run as more Democrats ask him to drop out

On Friday, Democratic Senator Martin Heinrich, of New Mexico, became the third Democrat in the upper chamber to call for Biden to step aside.

“By passing the torch, he would secure his legacy as one of our nation’s greatest leaders and allow us to united behind a candidate who can best defeat Donald Trump and safeguard the future of our democracy,” he wrote in a statement on X, formerly Twitter.

His statement follows that of Democratic Senator Jon Tester, of Montana, who called on Biden to end his re-election bid on Thursday.

“While I appreciate his commitment to public service and our country, I believe President Biden should not seek re-election to another term,” Mr Tester wrote in a statement on X.

In the House, Congressman Jim Costa, a Democrat from California, also called for him to withdraw on Thursday.

Democratic congressmen Jared Huffman of California, Marc Veasey of Texas, Chuy Garcia of Illinois and Mark Pocan of Wisconsin released a joint message on Friday saying “the most responsible and patriotic thing” Biden could do is “step aside as our nominee”.

“With great admiration for you personally, sincere respect for your decades of public service and patriotic leadership, and deep appreciation for everything we have accomplished together during your presidency, it is now time for you to pass the torch to a new generation of Democratic leaders,” they wrote in the joint statement.

Illinois Democratic congressman Sean Casten wrote in the Chicago Tribune on Friday that he doesn’t think the president can defeat former US President Donald Trump.

“It is with a heavy heart and much personal reflection that I am therefore calling on Biden to pass the torch to a new generation,” he wrote.

Two others joined the calls for the president to step aside on Friday – California Congresswoman Zoe Lofgren and Ohio Congressman Greg Landsman.

Reports this week revealed senior Democratic leaders are leaning in the same direction.

Senate Majority Leader Chuck Schumer, House Minority Leader Hakeem Jeffries and former House Speaker Nancy Pelosi have all reportedly expressed concerns during private conversations with Mr Biden about his candidacy. In public statements, Ms Pelosi’s staff insist her comments have been misrepresented.

Former President Barack Obama, Mr Biden’s previous running mate, has reportedly said Mr Biden’s chances of winning the election have greatly diminished.

Lawmakers haven’t been the only ones turning their backs to Biden. Big name donors – including actor George Clooney and Disney family heiress Abigail Disney – have closed their wallets.

Despite the defectors, some are sticking by his side.

New York Rep. Alexandria Ocasio-Cortez, one of the most influential progressive voices in the House, has supported Biden over the last few weeks. She broadcast live on Instagram on Friday morning and spoke about the risks of entering the convention without Biden as the presumptive nominee, including potential legal challenges and ballot access deadlines.

The Congressional Hispanic Caucus, which has about 40 members, and the 60-member Congressional Black Caucus, have both met with the president and also indicated their support for his re-election bid.
