MILWAUKEE — The biggest development at the Republican National Convention may be happening nearly 800 miles away, as the push to oust President Joe Biden appears to be once again gaining steam.

Rep. Adam Schiff (D-CA), who is running for Senate this year, became the latest Democratic lawmaker to call for Biden to step down as the party’s nominee. The number is now approaching two dozen, which might be manageable if Biden clearly had the support of the rank and file.
