Guess who may also suffer from this decision? Donald Trump.
Anyhow, ever since the U.K. voted for Brexit back in June 2016, there's been at least some doubt as to whether or not it would actually happen. Given the mandate and the majority that Johnson has just been handed, there is no doubt anymore. The U.K. is going, likely at the end of next month. Then, Johnson will try to negotiate what comes next, working from what certainly appears to be a position of weakness. In the short term, that will hit the British economy hard, and will likely send it into recession. The shockwaves from that, in turn, could drag the EU and the world economy down. It is not at all impossible that this plays out over a very short time, say six months. And if the U.S. goes into recession just months before the 2020 elections, well, that would be very big news, indeed.
Donald's support has been locked at a bit over 40 percent since mid-2018. The economy is one of his major selling points, if not his only major selling point. If that tanks just before the election...? His supporters don't care that much about details (or else they wouldn't give him so much credit--*cough**cough*Trade wars*cough**cough*), so his blaming the Democrats, the Fed, the world economy, the weather, the Patriots, etc. just won't fly very far.
And if he wins...he'll be
totally responsible, even if a recession doesn't hit until after the election.
So we'll see how that influences the next impeachment proceedings (you do know he's not going to stop ignoring the law just because the Senate acquits him, right?) if he's even more unpopular than he is now.
The UK's decision may be the camel that break's his straw back.
