It's clever, and Constitutional.
Because states decide how to pledge electoral votes, once 270 electoral votes worth of states say they will pledge to the majority, they pledge to the majority.
The rest of the states can pledge however they want, it won't matter.
It's clever, but short sighted (from a corruption perspective).
They've been relying on fraud to win the electoral.
They need the border open and amnesty to keep the popular vote.
Trump and his ilk are an existential threat… he's popular.
They should have just legislated to vote for the democrats.
