I'm happy to bet Trump's approval rating goes up. The media will spin it as if Puntin says that it's good than it Must be bad. This will be wildly popular with progressives on the left I'm a buyer of Trump's approval rating.
As of today Trump's approval rating on the RCP average is 42.4. His lowest in the last 18 months has been 37.7 and his highest 44.4. There isn't much upside left.
I think you're likely deluding yourself if you think there's going to be a wave of liberal progressives who suddenly flock to Trump over a decision to retreat from Syria. Especially as they come to realise that its all about Turkey and trying to strike a deal with them which prevents the Turks from heaping further embarrassment on Trump's beloved Saudi Arabia. Indeed, I note that even Joe Scarborough got himself on message today having spent yesterday pursuing links to Putin. I can only assume that someone has explained the real motives behind Trump's move as he cryptically referenced "events in a courthouse earlier this week" (which was of course a secondary motive that I alluded to yesterday given that Flynn was an unregistered foreign agent for Turkey cracking deals on their behalf)
The people you're describing "progressives on the left" are higher information voters, they aren't going to perform a 180 on this cynical move. These people have long ago decided what they think about Trump. Their minds are made up. If you're relying on them to win a buy position you're likely going to struggle, and before you commit to it, you need to also trade out any loss of support from his own supporters who lap up the idea of exceptionalism.
Also you need to factor in other things when looking at the approval rating.
As things stand, he hasn't got a Chief of Staff, hasn't got an Attorney General, has just lost his Defence Secretary, he's just shut the government down, the stock market has had its worst December since 1931 and he's just been ordered to close his foundation down for inappropriate function. All this in the last 10 days. He's got a total 17 legal cases in against him, plus six major investigations. Someone is sooner or later going to put two and two together about Stephanie Wolkoff as well. This is just an example of one of them!
For those unaware, she's a friend of Melania Trump whose line of business is party planning and event organisation. She founded WIS Media Partners in December 2016, (six week before the inauguration) and was paid a bit less than $26m towards organising the event. On November 19th, 2016, Trump agreed to settle the legal case brought against him for fraud involving Trump University for a total of $25m. Coincidence? We'll see. Has he really used WIS to funnel his legal settlement through using inauguration donations to pay off his fine?
Trumps in real trouble, trust me.
