Sorry, but they absolutely would.
They know they can’t win 2020, anyone with a few neurons working knows this... Sitting Presidents don’t lose unless you have a bad economy or something else of that sort of impact... and that’s not happening.
So, they can run a moderate, who will do the best, but lose, and see the far left wing say “See we didn’t go far left enough” and keep gaining more power and influence... or, they can get something out of this loss that will give them long term gain, and that long term gain is to knee cap the wing of their party they know can’t win a national election and is getting too powerful.
Which is what they are doing. Yes they may lose 2024, but they know they can’t win 2020... and something is better than nothing... If they don’t moderate they know they will lose 2024, and beyond.
Dems (at least the smart ones pulling the strings) know they are losing this fall... they also know, even if they run their best option for vote totals they will not take back the senate... Throwing 2020 in order to knee cap the far left, and let the party moderate going forward is the ONLY play to make... and they are making it... Pelosi’s little temper tantrum is part and parcel of all this as well.
If you think the oldest political party on the planet does not engage in strategic actions, you are completely underestimating your opponent. They know they have to moderate, or be on the losing end of national elections for a long long time... they also know they can’t win this fall... so, best play is to take out the AOC/Left wing radical idiot wing of the party.
As I said, if you think I am wrong, I ask you, please, tell me if you were a democrat, and someone told you, throw this election in the biggest way possible, without openly admitting what you are doing... What would you do differently than what the Democrats have been doing?
They know they can’t win 2020, anyone with a few neurons working knows this...
They absolutely could win this election. You tossing in a few pre-emptive "neurons" insults doesn't change that. But since you're one of those people who believes their opinions about future events to be uncontrovertible fact, I'm not going to bother further.
Have a Blessed Day!
