In the runup to the 2008 election, a particularly nasty ratfucking strategy was attempted, the assertion that Barack Obama wasn't born in the United States, and was ineligible to serve as President. The current occupant of the White House was one of the big proponents of this conspiracy theory. Conservatives being both racist and non-creative, one particularly weaselly MAGAt is trying to use the same tactic on Kamala Harris.
This sort of attack is a testimony to Ms Harris' strength as a candidate. There are some questions for Democrats regarding her tenure as California attorney general, but those are left-versus-centrist issues which will be worked out in the primary election. Ratfuckers like Wohl have no say in this matter, they are merely trying to poison the well, and the mainstream media outlets look like they are going to fall for this bullshit.
