Democratic aides say that Manchin can expect more tough treatment from Schumer and other Democratic lawmakers who are now under new pressure from the party’s base for failing to deliver on the “big, bold” agenda they promised earlier this year.

“He has had absolutely no pressure,” said one Democratic aide, citing Manchin’s friendly meetings with the at the White House and at Biden’s home in Delaware this fall that failed to produce results.

“Biden’s got to grab him by the lapels and say, ‘Listen, this ends now,’ ” the aide added, warning there’s little prospect of passing another piece of major legislation before the 2022 midterms if Build Back Better fails to pass.
