House Speaker Nancy Pelosi once described herself as a “master legislator.” Her critics have called that reputation into question after divisions within her own caucus left her unable to bring key portions of the president’s legislative agenda up for a planned vote last week.

Pelosi planned last Thursday to pass a bipartisan $1.2 trillion infrastructure package that is a cornerstone of President Joe Biden’s economic agenda. But, she was unable to do so when the party’s progressive faction threatened to defeat it unless their demands were met on a sweeping $3.5 trillion social spending bill.
