To be honest, I'd rather that they argue, bicker, and not pass laws. It's kind of funny, when you read the US Constitution, there are 13 things that the US Congress is supposed to do, and the rest of things are relegated to the States. However, when the US Senate became a 2nd House of Representatives in 1913, it was all down hill from there. There is no "second chamber of cooler heads," but a bunch of people kowtowing to the tempers of the People every 6 years, then back to 5 years of whatever they want to do (see McCain, John, Mister "Maverick "every 6 years, then Mr. "I want to be a Democrat too!" on the other 5.).
For those that say, "But what about the People? Why don't they get to elect the Senators?"
I say this, "You do have a House in the Federal Government. The House of Representatives. The States don't have any say in the Federal Government, but the Federal Government passes legislation that forces the States to do things. How is that fair?"
The federal govt is the glue that holds the "united" states together. State rights are not a free pass to ignore or over ride federal laws. Local laws should build on fed law and be tailored to improve local communities - not make them seem like another planet.
For example, fishing laws in FL relating to the Gulf of Mexico would be stupid in Wyoming, etc. On the other hand, air pollution does not respect state lines. If I CHOOSE to live in a state with strict clean air laws, why then should I be choked by the filthy air of a neighboring state that has deregulated as much of the clean air act as they legally can?
Federal laws set minimum standards so the quality of life across the country is not drastically different. What we see now is a race to the bottom with some states doing everything they can to keep wages low, pollution high and taxes low ONLY for the people with the most money. This is not sustainable, which is why so many people are finally waking up and lining up at voting booths.
