I've thought the Senate should be abolished for many years. So when I saw your post, my first thought was, "huh, a Trump supporter wants something good. Well, I guess even a stopped clock is right twice a day." I was disappointed when it turned out to not be true.
The Senate is an abomination rooted in the days when the states couldn't decide whether to be a confederacy or a republic, and so created a clunky, undemocratic, compromise design. The Senate should have been abolished right after the Civil War, when the issue was supposedly settled once and for all in favor of a republic. America had a huge chance to fix its design problems, but it was squandered. They settled for just ending slavery and made no effort to fix a single problem passed that.
