If there's any story it's that Trump hasn't done a good enough job yet of draining the swamp. He's trying to run off established Republicans that's why he didn't have a lot of support when he ran for office. Unlike the Democrat Party who will stick together even when they're doing the wrong thing, Trump isn't loyal to the Republican Party; he's trying to be loyal to the people he heard from on the campaign trail; this includes the deplorables.
Schumer is acting like this is all shocking news with the departure of some Republican legislators but Trump gave advanced warning before he became President. Oh, and here's a little something for some strange reason Schumer didn't mention (sarcasm), and that is so far there have been just as many Democrats saying they aren't running for re-election as there are Republicans AND the trend isn't any different than any other time. The Republican departures are certainly more dramatic because Trump helped make them happen.
I could start a news network that just focused on the leaders in the Democrat Party and over at the DNC, that covers how corrupt they are in misleading the American people. I'd have plenty of material every day to keep the show going strong. CNN's audience is going down so fast I'd probably end up with more viewers than them within a year.
