I don't think you understand how many polling places there are in America, and how they work.
So... you disagree with the U.S. Constitution. Cool. Good thing nobody has to care about your opinion.
The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.
Notice how literally nothing in that sentence gives the Executive Branch any power over elections.
The Federal Election Commission can only regulate campaign finance. They have nothing to do with the mechanics of voting. It says so right on their website.
The FEC administers federal campaign finance laws; however, it has no jurisdiction over the laws relating to voting, voter fraud and intimidation, election results or the Electoral College.

What is your plan for when that "mountain of fraud and disenfranchisement" doesn't appear?
This community was so fucking sure the Democrats stole the 2018 elections, and look how literally nothing happened. Trump seemed OK with accepting the results. He even claimed 2018 was a "victory" because GOP kept the Senate "and that's all that really matters."
Maybe you're just fucking wrong?
