I always enjoy watching committed leftists stepping on their own crank by committing that error.
Unfortunately, they have no shame. It usually has no effect.
That McCarthy was a heavy drinker isn’t really at question. McCarthy died of hepatitis, believed to be exacerbated by alcoholism. Was he an alcoholic, I guess I believe he was. There’s certainly a lot written of his heavy drinking. I have read that he falsely accused a black woman of being a communist and that Edward Murrow took him to task on the accusation. While he was likely right about many communists in the US and their subversive activities, we may never know who he may have falsely accused, since he refused to make public a number of names he claimed were communists. Truly an interesting person from the 50s
