6% shift though, that’s something. Most of his approval rating came from die hard people, so seeing a shift like that is really something. Important to see if that’s just short term shock in regards to the Capitol, or if these people will genuinely not support Trump in the long term. Impossible for us to see now though.
Republicans like Jim Jordan are already starting to whitewash the whole thing, along the lines that Trump never told these people to be violent, but the election was still fraudulent, and now on top of all this he's a martyr because Twitter et al banned him. And yes, events like these fade in public memory whereas "judges! abortions! Mexicans!" will remain very important to the base. The only thing that can dethrone Trump is perhaps another Trump-like character rising through the ranks, not sure who that could be though.
