If there's one thing Tierney Sneed and Lauren Fox found while reporting for us in Cleveland that I probably don't factor in enough in assessing the Trump phenomenon it's the deep resentment and bitterness Republican Party rank-and-file feel toward their own leaders for not fulfilling the extravagant promises made to them since the 2010 Tea Party revolt. I tend to focus more on the white resentment, race-baiting, and xenophobia that arise from the tectonic social shifts way below the surface. They're not decoupled from each other, but the promise that Obama would be put in his place (with all the accompanying racial overtones to that notion) and his political and policy agenda expunged from the public record were powerful GOP draws for three election cycles, as detached from political reality as those promises may have been.
You get a strong flavor of that intra-party resentment in Lauren and Tierney's dispatch from last night. We've written before about how the grievances nursed against Obama ultimately came to be redirected at Republican leaders on the Hill, and you certainly saw that with the booing of Mitch McConnell this week when he was on the stage. But their story is a good reminder on that point and captures it well.
