Here's what I don't understand.
If you know you are going to "win" the election anyway, why do you even allow someone with Stage 2 Dementia to not only run, but also become your front runner?
Anyone should know that the game is typically rigged before it even starts - regarding who the pre-selected front runner will be to become each parties presidential candidate.
Why the curve ball just to get Kamala? Why not just rig it for the blowjob queen in the first place and start day 1 with a willing puppet not confused thinking she is actually leading anything?
Obama was "awesome" in their eyes because he wasn't white. Biden was his VP. Biden reminds them of their "totally not racist" validation, thus Biden is easy front man to guarantee a nice chunk of votes. From personal experience, that's probably 15-20% of the vote.
