After being quieted for a short period, the doubters of President Joe Biden within the Democratic Party are making noise again.

A fresh batch of bad polling from swing states ... an underwhelming performance by the president in an interview on NBC ... and a stark warning from Burbank Congressman Adam Schiff are re-igniting calls that President Biden consider stepping aside in his reelection bid.

KNX chief correspondent Charles Feldman checked in with Tim Miller ... he's a columnist and podcaster with The Bulwark and former Republican strategist who is no fan of Donald Trump.  Miller gave his assessment of the fluid debate over replacing Biden.

Several elected Democratic officials lodged serious concerns about the Democratic National Committee's plans to formally nominate Joe Biden to the presidential ticket through a voice vote well before the nominating convention in August.
