One of the arguments I hear quite often against the possibility of change and reform in the Republican Party is that the party is essentially owned by a corporatist elite class, controlled by what Teddy Roosevelt called the "malefactors of great wealth." While the argument may have some validity in that corporate interests have invested heavily in the Republican Party, there is a fundamental illogic in assuming that this means that the liberty activist wing of the party can't make great inroads and even initiate revolutionary change in the party.
The proponents of this argument use as their examples the efforts of the party to pursue policies beneficial to certain business interest groups, usually the oil industry. They point out that Republican support for the Keystone Pipeline and for expanded oil and natural gas exploration are motivated by the influence of powerful corporations or super-rich families like the Koch and Bush clans. Similarly, opposition to trade controls, union busting, lax immigration laws, deregulation of industries, opposing environmental regulation and favorable treatment of Wall Street – all Republican policy mainstays – all benefit corporate interests and the wealthy groups behind those corporations.
All true, and all entirely irrelevant to whether those powerful interests would allow a libertarian wing of the party to gain more influence, elect people to office and change the ideological emphasis of the party. The key thing to consider here is that these plutocratic interests are not motivated by ideology - money has no morality. They are motivated by the desire to make money and to be left alone by government in order to do so. They want the Republican Party to clear the path for them to achieve their goals. Traditionally they have done this by corrupting politicians, spending money on campaigns and on buying influence to get what they want. Therefore, what reason is there for them to oppose a political movement within the party which produces leaders and policies which are inherently more compatible with their interests?
