There are exactly two black Republicans in the House: Will Hurd and Mia Love.
What's insane about Elijah Cummings? This is an honest question; I don't know much about him.
I'm not much of a Love fan. I've always felt like her message was "I'm black but don't worry, I'm not like those other black people". Will Hurd represents a Hispanic area in Texas on the Rio Grande.
Cummings had some tirades in House committee sessions that made him look pretty bad. I don't know specifics. I'll just admit right now that I follow the Senate a lot more closely than the House. It's just a lot harder to follow 435 people who are up every two years than 100 people who are only up every 6 years, and anything the House passes must make it through the Senate anyway.
