It took just 48 hours for Kamala Harris to secure support from enough Democrat delegates to take the party’s nomination from Joe Biden. But the coup was set in motion weeks ago, with party operatives plotting to use his mental decline to force him out.

The numbers: Harris has secured the support of at least 2,668 Democrat delegates, according to an unofficial tally by the Associated Press. That far exceeds the 1,976 needed to win the nomination and makes her the presumptive nominee.
