Is Donald Trump getting closer to impeachment?

It doesn't seem to matter how bad the news is for Trump on the Russia collusion/payments to porn stars/dodgy deals to keep alleged mistresses quiet front, the president dismisses everything as a witchhunt or lies or both. Michael Cohen, his very ex legal chum, has come in for the full Trump treatment. Everything he is being quoted as saying to his lawyer about Trump ordering him to pay off women, let alone his apparent willingness to talk about Trump and Russia collusion, the president poo poos and laughs off. Cohen, one-time trusted lawyer and Mr Fix-it, is now the scum of the earth in Trump's eyes. It's almost impossibe to make a judgment about whether Trump is on the slippery slope to impeachment or just building a bigger and bigger wall around him to keep all his political enemies and former friends at bay. Impeachment is a very big word, too big for most people, especially if you're a Republican. So, provided the Republicans keep their majority in the House and Senate, it ain't going to happen. But if the mid-term elections have some surprises and the Democrats slip into the lead, who knows what might happen, although even then, some Republicans will have to agree to go for Trump. The Cohen affair will run all the way to the elections in November and by then someone else will no doubt emerge as the new bete noir of the president. Can Trump dismiss everyone as liars and witchhunters? I guess he can. He is the president after all.
