That is what we did with Reagan LF! It is how the Reagan revolution came to be and coined the phrase "Reagan Democrat".
McCain is planning the exact same strategy and other may now have to do the same.
This event may be the catalyst that makes that possible.
You are wrong to thing that a Reagan Democrat likes RINO's. As evidenced my Reagan's success, they like straight shooters.
All of the 'Reagan Democrats' I know are and have been union workers that are as conservative as Ann Coulter, have NRA stickers on their trucks, right next to the Union Yes stickers.
McCain will fail as miserably as Gerald Ford did in the 70's.
