Agree. What I would do with his money, at this point, is to hire the best people he can find (and can trust) to tackle each major policy issue and to provide specific policy documents that are written for public consumption. Then go straight the people with these.
Health care, immigration reform, trade policy, an economic plan, AND a very specific new approach to deal with political corruption and capital cronyism, for starters. Every week a new policy document that points out what's being done wrong, and goes after it in a practical manner like a business would. Tell the people directly that it will no longer be business as usual. That many of them voted for Obama because of the promise of Hope and Change, but got more of the same. He should pledge that he would absolutely change the corruption, the insider control, and give government back to the people.
In other words, he has to position himself as a highly competent populist who loves America.
Yes, that is a wonderful strategy. And if he does decide to play arsonist, he should name names just as he did his primary opponents. Burn down Ryan, Pelosi, McConnell, Flake, McCain, Graham, etc and do so at rallies in their respective states. They need to be uprooted like weeds and tossed aside.
