Article 1 section 4 clause 1 of the US Constitution states .. time, place and manner of election of senators and congress shall be prescribed in each State and legislature .
As we saw during the Capital Hill riot or insurrection whatevet you want to call it, the Federal legislative branch had a obligation to certify the results once the elections have already taken place in the states. Too late to make a difference despite what the last President thinks.
Some partisans want something to be DONE about the unfair elections. Don’t expect the state legislators to surrender their privilege to set election rules to the Feds.
