This is a nothing decision, there have always been so-called “Faithless Electors”; Trump had 2 R Electors not vote for him in 2016, and Hillary had 5 Faithless Electors.
Of course, this still benefits the D’s by not outlawing Faithless Electors, and despite the 2016 results of the R’s ‘winning’ the Faithless Elector battle 2 to 5; historically, there are more RINO’s than Blue-Dog Democrats who would be willing to not vote for their party’s nominee.
