Anyone who does not have their own money is beholden to their donors.
Walker is no different.
Most of our government falls into that category. Lobbies Political donors. Funds doled out by GOP at their discretion
Walker has done good work in Wisconsin.
He is however, a beggar for campaign funds like most of the others.
To get cash he will have to pledge his allegiance to the RNC.
If they give up on Prince Jeb, Walker is their Plan B.
