Remember that time when Sen. Kamala Harris attacked Joe Biden on the debate stage and asserted that while he wasn’t quite a racist, he was all too happy to work with segregationist lawmakers to oppose mandated busing in the 1970s?

It was a brutal moment that saw Biden’s poll numbers drop sharply while the California Democrat’s shot up, making her suddenly a leader in the Democratic field for the 2020 presidential nomination. Harris took it seriously, even going so far as to have “that little girl was me” T-shirts ready the night of the showdown for sale to supporters. Now, Harris has endorsed Biden after a gangbusters Super Tuesday showing for the former vice president.
