So, as I predicted, President Donald J Trump has been impeached by the United States House of Representatives 230 ~ 197 (1 abstention and 3 not voting) (216 needed to impeach) to on the first article. (Voting on the 2nd article is underway as I post this.)
He is only the third president in US history, after Andrew Johnson (17) and Bill Clinton (42) to have been impeached. (Articles of impeachment had been prepared against Richard Nixon (37) when he resigned.)
President Trump wrote a long letter to Speaker Nancy Pelosi which laid out, pretty well, actually, his case against impeachment. It did no good in the House; it will help keep Senate Republicans onside. As he pointed out in his letter, senior Democrats have been working for impeachment ever since he was elected.
My second prediction (first link), which Senate Majority Leader Mitch McConnell seems to have confirmed, is that he will be acquitted at trial in the United States Senate.
Americans seem deeply and evenly divided about impeachment, as they are in so many things. My guess is that this issue will solidify opinions on both sides: those who hate President Trump will hate him even more because he will have been perceived to have weaselled out of impeachment; those who support him will do so with increased fervour because they will regard the whole process as being unfair and unjust. The consequence is that Donald Trump is very likely to be re-elected in 2020 which means that Canada will have to deal with him, across the entire spectrum of policy and political issues, for four more years.
