For better or for worse, I can name a lot of sitting Senators, from memory: Rand Paul, Mike Lee, Marco Rubio, John McCain, Harry Reid, Barbara Boxer, Dianne Feinstein, Orrin Hatch, Patty Murray, Mitch McConnell, Lindsey Graham, Lisa Murkowski, Chris Murphy, Kristen Gillibrand, and uhhh... that's all for now. Two years ago when I followed politics much more closely and might have named over 50. Thankfully, I have better things to do these days.
P.S. How did I forget Ted Cruz... oh well, he's just another scumbag.
