Actually, you are completely wrong. The GOP (with the single exception of Ron Paul) has no ideas. That is why they use the Democrat's ideas and try to underbid them.
The ideas that Ron Paul espoused (i.e., peace and individual liberty, sound money and small government) do appeal to people. But the GOP rejects those ideas because the GOP is a fascist party (just as the Democrats are) that is married to the military-industrial complex.
PS: When I say "Fascist", I do not mean Nazi. I use it in its economic sense.
