Because the house wasn't electing them. They had separate priorities. Currently they are more beholden to the party because of the funding they need to run. More of a rubber stamp than before.Should the Senate represent the people or another group of leclected representatives. If they are elected by the representatives why would they not just become a rubber stamp organization for the house ?
And yes, Darla, many of the things the States did were awful. I believe that there is, and can be, a better compromise than making the US into a homogenous entity.
