McConnel's plan is easy to see. If he attaches the repeal of 230, the dems will suddenly be against it, and thus, when the bill dies because the democrats won't vote for it because of the attached pork, he can shift the blame on them rather than having to face the threat of the Republicans not backing the money increase in the Georgia elections. And he gets back in Trump's good graces because "Well, I, your good friend Mitch, wanted to give you everything you wanted, but the meanie Democrats fucked it up".
