Don't forget that the billionaire may support a minority view that wouldn't be heard with campaign limits. Democrats and Republicans are far more likely to be able to deal successfully with campaign contribution limits than small independents or third parties; both the major parties can make it up on volume, but a smaller voice... not a chance on those terms. Campaign limits is actually one way that the legal system entrenches monied interests in the political system rather than disconnecting them. This is why there is such a convergence in the governing outcomes of the two major political parties in the U.S. The larger issue with money in politics isn't that people can spend money on speech: it's that often times that the access money buys is worth the price. Too much control by a government and there will be those that want to have their voices heard and can afford to do so.
