My first thought was why would a man with a job like this put this on liberal tweeter and not expect push back from the liberal media. He most likely will lose his job over this.

Secondly, something tells me this MLB umpire is not alone in his thinking. After all this democrat impeachment process they are holding is why our Founding Fathers gave us the 2nd Amendment in the first place.

Third, the "red flags" are going to come and take his new shiny AR-15 away.

CIVIL WAR! Major League Baseball Investigates Pro-Trump Umpire

Major League Baseball is investigating longtime umpire Rob Drake after he posted a message on Twitter suggesting there would be a civil war if President Trump was impeached.

Drake tweeted that he planned to buy an AR-15 rifle "because if you impeach MY PRESIDENT this way, YOU WILL HAVE ANOTHER CIVAL WAR!!! #MAGA2020"

I'd love to think Americans would take up arms to Defend President Trump.  I'd be up for it, personally.  I'd prefer to see a few million Patriots march on the Capitol Bldg, and grab each and every member of Congress, and give 'em an ultimatum.  "Go Home, and never Return, of we'll Throw you and your offices in the streets, expeditiously."
Congress is the problem.  Both sides of the aisles in both Houses.  The Dems are the Do Nothin' Party and the Pubbies have no Collective Spine, so to speak.
We need Term Limits, and new blood in Congress.  These embedded Congress Critters are using us, and it is High Time it stopped.
As far as Pro Sports, I have given up on NFL, MLB, and the NBA.  I still watch the NHL, Tennis and Golf.  Yeah, how boring.  Maybe I'll develop an interest in  Curling.  Just Sayin'.
