If Democrats succeed in enacting the White House’s agenda, they will have dramatic accomplishments that would both boost party morale and demonstrate they delivered on their promises, many of which are popular with the American public.

But trillions of dollars of additional spending, higher taxes, an increase in the debt ceiling and a more expansive government would also open Democratic officeholders to GOP attacks in politically competitive states and districts.

Even worse, if Democrats fail to deliver on infrastructure and/or reconciliation (most likely because party moderates and progressives can’t agree on bottom-line spending), Biden will look weak. That outcome would fuel the narrative that Democrats are divided and ineffectual, which would severely damage the party’s midterm prospects…

But the administration’s list of headaches continues to grow, now including confusion over COVID-19 vaccine boosters, trouble at the U.S.-Mexico border and Biden’s inept rollout of a new U.S.-U.K. agreement to sell submarines to Australia.
