I agree with the gist of your very excellent post here.
One other thing the Democrats have is younger insanely wealthy supporters from Silicon Valley like Zuckerberg who are willing to spend millions to get Democrats elected, plus they have a mindset of trying new and different things that make a huge difference
Republicans are still running campaigns like it’s 1980 instead of 2024
Republicans are still running campaign ads that cost 10s of millions that do little if any good, Democrats spend their money on election lawsuits trying to force election laws to be changed in their favor and front groups for ballot harvesting and other political activities
In a presidential campaign the democrat barely has to campaign to get 81 million votes, I would estimate 8-10 million votes for Biden were fraudulent maybe less but enough in battleground states to swing the election
I have begun to believe that Biden did get 81 million votes, 81 million actual ballots went through machines but millions were fraudulent
Republicans can fight this in a couple of way, technology exists to scan voter rolls looking for people registered to addresses that no one lives at like vacant lots and multiple people registered to the same address
The Republicans can also engage in vote harvesting where it’s legal
Republicans choose to do nothing and will continue to lose elections that could be won if they ran a modern campaign
