You are sounding a little bit like a Democrat, friend FReeper. Remember that it's not the Senator's job to get himself re-elected. That being the case, it's not even the Senator's job to do what the majority of his constituents want him to do.
In short, it's his job to do what is right, not what is popular. This is axiomatic in the idea of a Republic.
So, I don't plan to cut the RINOs any slack whatsoever. If they aren't going to do what is inarguably right--i.e., eliminating double taxation--then they need to leave the Senate and start working for a living for a change.
(RINOs aren't ideologically dumb. Heck, they are ideological prostitutes. The funny thing is, they manage to convince themselves that their hyper-democratic ideals are okay ["We have to do the will of our constituents!"), whereas their position is ultimately self-serving. They are essentially just Democrats who have discovered that they have a better shot at getting elected if they run under the name of Republican.)
