Dole is a Rockefeller Republican as is/was Ford. They are pro-social program expansionist, moderate to liberal on most social issues, and in general expand government agencies well beyond the need. Snowe, Chaffe, Jefford was, Frist, Lott, McCain and quite a few others are Rockefeller Republicans.
I did some look ups and Grand Pappy Senator Prescott Bush was also a Rockefeller Republican supporter as well :>} I found a good definition of it here http://www.baltimoresun.com/news/nationworld/chi-0408310265aug31,0,6425892.story for anybody that wants to go there.
If a person can understand that a minority within the GOP is taking down the majority with it then things might change. These two factions are two as different as night and day. Most of the GOP the Conservative and the Rockefeller Republicans the minority but seem to have the Lobby Money.
The Grand Old Party is also referred to as "country club republicans". The minority, Rockefeller Republicans, control the money of the GOP. Many are wealthy, not just rich, but wealthy. I shutter to think who the GOP presidential nominee will be.
