After next year, run for office. Winning is unlikely, but perhaps one can at least promote some debate. One of my friends is/ was a "consultant" for local republicans, his regular job as a grant writer and consultant had him researching opinion, rules and regs etc to apply for various government or private foundation sources of money. He was one of the "handlers".
The candidate himself was a physician, a surgeon, and I am sure a bright man. He had a genuine interest in reforming or changing one or two issues. The rest was pretty much a blank slate. My "friend's" job was to get him elected, and to guarantee what was filled in on that "blank slate". He himself was not nearly as interested in any one position as he was in winning. If his man won, his stock and worth just jumped several notches, his fees increased , he was in more demand. He WAS financed however by persons who DID have a very keen interest in many issues, and they were willing to pay nicely to see that position filled in that blank. I wanted to talk to the doctor, I had met him in the community a few times. I was at a fundraising dinner ( cheap one-$25 donation)and my friend was there with him. I wanted to talk about some medicaid issues that I happen because of my job to know a lot about. I had played golf on the same 4 man team with him for 3 years. He acted like he had never seen me before in his life. I got about 30 seconds and the good doctor was dragged away by my "friend" over to the deep end of the pool where the $500 dollar guys sat.
I don't know if anything CAN be done at this point, lest fate brings certain issues to collide in some perfect storm that generates a huge ground swell of opinion that can overrun party dogma and propaganda.
