How? First off, Harris isn't Biden. No one is confused by this, but maybe you are because you think Harris must have the exact same stances and opinions as Biden. Second, it wasn't just "tankies" who were upset at Biden's enthusiastic support for genocide. Anyone with any shred of decency is against genocide. Finally, people like you claimed that Biden was our best chance to beat Trump and insisted that we all had to throw our support behind him because Trump is worse and that anyone criticizing Biden for supporting genocide is a tankie. Turns out that him dropping out to make way for a better candidate actually works and many Americans are excited that we don't have to support such a garbage candidate just because the other side has a worse candidate. The positive reaction to Biden dropping out was immediate and clear.
Damn I was wondering when the person against Biden dropping out who I talked to bit ago went. You're certainly still convinced Biden was the choice right?
I'm afraid you have me at a disadvantage, I don't recall our conversation. My opinion has definitely changed on this topic though. I'm glad he dropped out.
