Not to mention the constitutional confusion. Declining the winner of the EC would either leave the country without a President, where maybe duties fall to the Speaker of the House, or let the House pick someone. Does the US even have a mechanism for calling an early election to get a replacement vote?
Still, I expect pundits to bring it up as a mechanism to satisfy SCOTUS. They have a lot of air time and blog space to fill before the election (nevermind the inauguration), and baiting the MAGA crowd with a Democratic Jan 6 insurrection will certainly drive engagement.
