Senators are FAR more important then Congressman.You may be right that they are more powerfull then a governor.However,for ANYONE to imply a congressman is more powerfull then a governor is just plain stupid.Perhaps someone can name the congressman that came right out of the congress and became president.There is a reason why.
IMO, as a whole, congressmen are more powerful than the group of governors.
They have just as much say in starting wars, health care, cap/trade, etc etc, as senators. Everything the senate sees must pass the house first.
I wish the governors had more power, as they are really more independent and more in touch with the needs of the people. They wield a huge sword in their own state borders. But their changes don't seem to be as permanent. You can't "undo" universal healthcare, social security, medicare, or Iraq, like you can change state law on things.
