If we assume that, in theory…as an example, Biden were to abuse the ruling and if we also assume he means well; he could theoretically do the following:

• Simply round up Trump, all his major supporters, major far-right republicans and anyone else who has been making large moves that support the treasonous and seditious acts
• Declare all of them terrorists, seditionists and traitors to the country
• Recommend that the DoJ immediately arrest them, find them guilty, and sentence them to exactly 4 years of prison for each individual seditious anything they were doing, or perceived to be doing.
  • Most of the powerful ones would be serving multi-decade sentences probably.
• Get re-elected, push through bills to patch up any and all loopholes they used to undermine the system of government.
• Step down after the term and retire from politics after having put down their rebellion.
