Trump is not infallible, and honest criticism of him from the right is going to happen, like it or not.
The rest I agree with, but there are problems with the remedy: The STATES control the manner and method of choosing electors, and run their own elections, so the reforms you've suggested, while I fully agree with them, cannot Constitutionally be forced on the states by the Federal government.
I would add one additional reform, which can be done by the Feds: the Constitution mandates that the Federal elections of the United States must be held on a single day throughout the country. Early voting is Unconstitutional, and we need a Federal Law stating that, which at the very last should be tested in the Federal Courts. Early voting is a huge source of fraud.
I did not know that.
