From raising alarm to backing Biden, Democrats in Congress grapple with debate aftermath

President Joe Biden’s disastrous debate demeanor last week has reverberated across the Democratic Party. It is forcing lawmakers to grapple with a potential crisis that could reach beyond the results of the presidential election. The Democratic president has signaled he has no intention of dropping out of the race against Donald Trump, despite the halting and uneven debate delivery that threw a spotlight on questions about Biden’s age and capacity to be president. Some Democrats in Congress are raising concern over Biden's ability to show voters he is up to the job. Others are standing firmly behind the 81-year-old president.
