They may be pushing this but at this snippet in time, WE are the future of the republican party. It's not glamorous nor is it always fun. But the party is ripe for "taking over", which should actually be called taking back, and it starts at the local level.
There are plenty of examples right here on this board of RPF members becoming committee chairs, passing resolutions, and making other significant changes in their local committees.
There is a lot of grumbling and disgust among conservative republicans. They KNOW they've been hijacked but they really don't know what hit 'em and many are afraid to speak up. So, stand up, speak out and effect change. I think you'll be surprised at the positive response you'll get (I was!).
Focus on their stated principles, leave the controversial issues aside, and you'll have many of them eating out of your hand.
Ron Paul has mentioned several times recently that fellow congressmen, who have before now just been barely polite to him, are now coming to him to find out what all the fuss is about. We HAVE already made a HUGE impact. Ron Paul has an opportunity to educate them; we have an opportunity to educate local republicans. It's a challenge, for sure but nobody ever promised that this would be easy. In this r3VOLution, there is no such thing as instant gratification. It's one small battle at a time.
There may very well be a point in the future that we need to make a mass exodus from the party but that time is not now.
