With Joe Biden out, what’s Kamala Harris’ path forward? | Power & Politics

Joe Biden's campaign has been thrust into a pressure cooker of doubt, as panic and worry about his election chances pour in from the highest levels of the Democratic party.
In recent days, Senate Majority Leader Chuck Schumer, House Minority Leader Hakeem Jeffries and former House Speaker Nancy Pelosi have all reportedly expressed concerns in private to Mr Biden about his candidacy.
Even his former running mate, former President Barack Obama, has reportedly said Mr Biden's chances of winning the election have greatly diminished.
A 6 July letter from high-ranking congressman Jamie Raskin was made public on Thursday, where the Maryland representative compared the president to a baseball pitcher whose arm has "tired out".
Mr Biden, 81, has repeatedly and defiantly declared he is "not going anywhere", urging his party to refocus on the task of defeating Donald Trump.
But the calls to exit are nearing a crescendo as Democratic politicians, donors and voters speak out against the president's candidacy.
