We'll see if that holds true.
Because party reigns supreme in politics far more than ideology, this is why we almost always see ideology go by the wayside for party loyalty and to vote the "party line." Witness the democrats who voted for the health care bill, even though they opposed most of it. Dennis Kucinich was a great example. Witness the republicans who voted against it, even though many were calling for many of the same reforms in years prior to the current bill that was passed. Iowa's very own Chuck Grassley was a great example.
This is why I vote party first, and ideology second, as that's how the game is played. (However, I will never vote for a Clinton to preserve party, but will simply write in my own candidate!).
