At least for the party leadership, I think that's true. However, there are at least a couple who are willing to run against the grain on the state level who may trickle up over the next decade.
I'd like to know whether people think the push for a constitutional amendment on money in politics or at minimum stronger legislation on campaign finance is possible. I get the general feeling this crowd is at minimum skeptical of it. Hell, it was one of the things VRWC and yours truly agreed on.
I'd hypothesize the threat of an Article V convention can be effectively used to force the issue, but it's going to take a lot more than the 5ish states considering it now to do so. A decade may be too soon, but the process could be in motion by then.
