With Biden out, is Kamala Harris the Democrats’ trump card for the US elections?

Tiny cracks in the Democratic coalition quickly became an insurmountable chasm for President Joe Biden following his disastrous debate performance on June 27. As a result, Biden became “the first sitting president to stand down from a possible reelection since Lyndon B. Johnson in 1968.”

Announcing his decision to bow out of the US presidential race on Sunday, Biden quickly endorsed Vice President Kamala Harris — a decision that is likely to put to rest the internal divisions roiling the Democratic Party.
