Leading Massachusetts liberals like Elizabeth Warren and Ed Markey who have plenty to say about Donald Trump have been mysteriously silent on whether a besieged President Joe Biden should stay in the race.

Sens. Warren and Markey are AWOL on the Biden debate engulfing the party, showing no spine as they watch the Democratic presidential campaign spin out of control.

Other Democrats like House Whip Katherine Clark have also vanished — leaving it to others to comment on Biden’s diminishing mental faculties.

Gov. Maura Healey, after days of public silence, finally put out a wishy-washy statement saying Biden has to “carefully evaluate” whether he’s the best hope of beating Trump – but stopped way short of calling on him to quit the race.

Healey reportedly was much more forceful in private, telling fellow governors that Biden’s campaign suffered “irretrievable” damage on the debate stage – implying he could no longer win. But she publicly now won’t say the same thing. Not much of a profile in courage.

Healey has been one of Biden’s top surrogates on the campaign trail and she now appears afraid to add to the president’s grave political problems.

Warren and Markey’s silence is especially notable considering other Democratic lawmakers like Massachusetts Rep. Seth Moulton have called on Biden to step aside.

Moulton is the only one with enough spine to publicly distance himself from Biden, and acknowledge what 80% of Americans now believe – that Biden doesn’t have the mental and physical stamina to take on the former Republican president.

But other Massachusetts congressional lawmakers have not gone that far.

“[Biden] needs to consult with fellow elected officials and with public opinion research to determine if he is the strongest candidate to defeat Donald Trump in November, which is the unifying imperative for the Democratic Party,” U.S. Rep. Jake Auchincloss said in an interview with GBH News.

Consult with polls? Really? The polls are already pretty clear that the Biden campaign is cratering.

Biden, meanwhile, continues to dig in his heels and refuses to drop out, telling a rally in Wisconsin: “Here’s my answer: I am running and I am going to win again.”

Biden of course couldn’t get through the speech without a gaffe, saying “I’ll beat Donald Trump. I’ll beat him again in 2020.”

But reading a rally speech from a Teleprompter is not the same as winning a debate or holding a press conference and making sense.

With big money donors already bailing on him, Biden needs to do something drastic to save his campaign and sitting with a Democratic sycophant like George Stephanopolous won’t cut it.
