This is not normal. It should never become normal in America. If you're wondering what to do, find out who's running for Congress where you live. Are they a Democrat? Then support that person as best you can. Make sure you vote in the primaries this year after you check and make sure you are registered to vote.
In November, idiots like me are going to be screaming at people to go vote. Please help us, please join us, please resist along with us, and please vote to throw the Republicans out of Congress.
