I agree that Trump’s influence may be declining – and as the months go on and the investigations reveal more, the Republicans may be emboldened to take further action against him.
A censure of Trump with real legislative teeth behind it, perhaps in conjunction with section 3 of the 14th Amendment (which would prevent him from running for office again) would only require a few of the seven Republicans who voted to convict regarding impeachment to agree to censure Trump in a serious, meaningful way.
This strategy is actually politically possible and I am continually updating it as events evolve in The War After the Election [https://medium.com/illumination-curated/the-war-after-the-election-545de96aa4ca?sk=627c55d616d9296af3e398f1686493a4] and in a link at the end of it which explains the legislation that could be attached to the censure.
This strategy would address the just as important underlying national security problems regarding the Capitol attack which haven’t been investigated, let alone resolved. Apparently the Department of Justice is considering using RICO charges to connect the conspiracy dots regarding what led up to the Capitol insurrection.
