Don't bother. Trump supporters are immune from logic, reason, empathy and facts...

Trends often take years to show up. There are things in play now from policies that go back nearly 100 years. Trump inherited a economy that was ramping up, and nudged it even higher by costing the country trillions in revenue, spending our international goodwill, and moving funds around from sources such as FEMA. Even then the middle class are suffering even with GDP and unemployment booming.

I could go on for quite awhile but there is a fair summary here that has plenty for you.

!. Research the increase in the economy, specifically the U.S. stock market from when Obama started until he left. Idiot trump just took over the train already moving.
2. Jobs--Obama created 3.5 or so million, Trump 3.2 or so but easier for him because the econmy was already moving because of obama
3. the idiot pulled out of the climate change agreement with the rest of the world...is he the only smart one? of course not
4. The idiots tariffs are hurting many industries here and pissing off our neighbors, mexico and canada. Research harley Davison moptrorcycles moving out of the u.s. because of him. The auto industry can't get parts ot make our cars because of the tariffs.
5. He hasnt filled most of the government positions still open because he's played golf some 100 days. Research the video of him bashing obama for playing golf, saying he\'d be too busy and the look up the number of times he's played before
6. He is an unindicted co-conspirator in the felony of election fraud according to the guilty plea of the guy who helped him in the fraud.
7. I can go on and on but I bet your friend knows what part of the world Israel is in. Here's where you get him. After you have dumped all the stuff I just wrote, ask him what part of the world israel is in (middle east of course) When he gives you that answer say, do you think the president of the united states should know the answer to that question? When he says yes. Ask and if he doesnt wouldnt he be an idiot? He better say yes otherwise you'd have an idiot running your foreign policy. Then play this tape for him. To set it up, the idiot is in Israel talking to a room full of Israelis and he just came from Saudi Arabia. To see that even his staff knows he's an idiot, chck out the guy on the couch to the righ when he says it--who runs his hand through his hair like "who is this idiot."

The man also lies 7-8 times a day since he's \been in office--the washington post is keeping track, you can find it.
Enough for a start?

I defriend and block all people who are Trump supporters..even relatives and childhood friends. I don't talk to them or engage with them at all.
