The pressure campaign by Democrats and the media to convince President Joe Biden to step aside as the party's 2024 nominee has continued to grow in intensity, even as the prospective details on how and with whom he would be replaced at this late date are still being worked out.

One recent voice to join the chorus is Rep. Zoe Lofgren (D-CA), who suggested that potential replacement candidates for Biden could go through a brief "mini-primary" and be vetted by former Democratic Presidents Bill Clinton and Barack Obama, according to The Hill.

The effort to replace Biden began in the wake of his disastrous debate performance against former President Donald Trump last month but has been complicated by the incumbent's steadfast defiance and refusal to drop out in the face of mounting pressure.

Congresswoman suggests Clinton and Obama could vet possible Biden replacements

The Hill reported that Rep. Lofgren sent a letter to President Biden on Thursday that spelled out her reasons for believing that he should step aside as the Democratic nominee and allow somebody else to represent the party in the upcoming election against former President Trump.

"As I am aware that you have been provided data indicating that you in all likelihood will lose the race for President, I will not go through it again," the congresswoman explained. "Simply put, your candidacy is on a trajectory to lose the White House and potentially impact crucial House and Senate races down ballot."

On Friday, Lofgren appeared on MSNBC to discuss her letter and the push to oust Biden as well as how his ultimate replacement would be chosen, and said, "Should he make that decision" to drop out, "there will have to be quick steps" to replace him.

"I don't think we can do a coronation, but obviously the vice president would be the leading candidate," she continued in reference to VP Kamala Harris. "I think kind of a mini-primary, maybe vetting hosted by former presidents, including Obama and Clinton, would be helpful and help focus the attention."

"And whoever emerges, including Kamala Harris, would be a stronger candidate than if we tried to exclude a transparent public process," the congresswoman added.

Congresswoman calls Trump a "threat to America and the world"

Earlier in the interview, Rep. Lofgren told the MSNBC host of her decision to come out publicly against President Biden, "I think from the data it's pretty clear, as I said in the letter, that the president is on a trajectory to not prevailing in the election."

"And I think it's telling that members of the J6 committee -- myself, Adam Schiff, Jaime Raskin -- have all suggested that he step aside, and that we get another candidate who can beat Donald Trump," she continued.

Just days after a would-be assassin attempted to kill the Republican nominee, undoubtedly spurred on by over-the-top anti-Trump rhetoric, the Democratic congresswoman added, "Donald Trump is a threat to America and the world. He cannot be elected. He must not be elected."

At least 34 elected Democrats have called for Biden to exit the race

According to CBS News, as of Friday, there were at least 34 elected Democrats -- 30 House Democrats and four Senate Democrats -- who had publicly called for President Biden to drop out of the race and end his bid for re-election to a second term in the White House.

It is rumored that several more Democratic lawmakers have either privately urged Biden to step aside or have quietly shared their doubts with others about his abilities to not only win but also govern for another four years in office, but have thus far refrained from doing so publicly.

Of course, all of that is a moot point if Biden refuses to heed those calls and remains in the race, in which he currently trails his political nemesis Trump in the national polls by an average of three points, according to RealClearPolling, but perhaps more importantly by roughly two to six points in all of the most important battleground swing states.
