Getting rid of or adjusting the Senate membership has even less of a chance of happening than getting rid of the Electoral College. It absolutely will not happen under any circumstances whatsoever. Ever.
Sheesh! Some of you people need to read up on how this country was founded -- the good and the bad -- as well as study the Constitution thoroughly.
As a student of History, I do understand. I was referring to a growing popular movement who apparently believe the Senate gives low population states an unfair advantage in determining what they see as the will of the people.
All it would take is an Amendment to get rid of the EC, and another one to change the way the Senate is apportioned. We already had an Amendment to change the way Senators are appointed / elected. Give it enough time, the US may see the day when California has 40 senators and Wyoming has 1.
