Walter Olson reviews them and concludes:

Among Ramaswamy’s four election reform planks, one is years behind the times; one doesn’t have the advertised effect; one would take away convenience valued by the public; and one is a dubious wish list item of unions and liberal pols. All four, by imposing a uniform national standard, would override states’ discretion to adopt policies reflecting local preferences and circumstances, even though Article 2, Section 1 of the Constitution is careful to reserve almost entirely to the states the key steps in electing the president. There is no evidence that any of the four measures, or all four together, would have changed the result in the 2020 presidential election, or in any one state.

Ramaswamy says that Mike Pence should have refused to certify the electoral votes from the 2020 election unless Congress put these ideas into law.
