Some thoughts on what havoc unleashed billionaires might have on elections in the wake of the Citizens United decision, It also provides some interesting insight into the difference between the two parties organizationally:
While, the rapid growth of well-financed and autonomous competitors threatens all existing power structures, the bulk of the costs are likely to fall on the Republican Party. The right wing of the Republican Party has more disruptive potential than the left wing of the Democratic Party because it is more willing to go to extremes: see the billboards showing Obama bowing down before an Arab Sheik, or the ads and DVD claiming that Obama is the bastard son of the African American communist, Frank Marshall Davis.
There are, furthermore, structural and historical differences between the parties: the Republican Party and the conservative establishment is institutionally stronger than the Democratic Party, with an infrastructure that served as a bulwark through the 1960s and 70s – the American Enterprise Institute, the Heritage Foundation, the Cato Institute, the Olin Foundation, etc. — when Republicans appeared to be a permanent congressional minority. Its financial prowess enabled the party to enforce more discipline on its consultants and elected officials. The Republican establishment also exercises more authority over policy and candidate selection than does its Democratic counterpart.
In recent years, the Democratic Party organization has gained some strength and it plays a much more active role in campaigns at all levels than in the past, but as an institutional force capable of command and control, it remains light years behind the Republican Party.
Republicans, in contrast to Democrats, prefer hierarchical, well-ordered organizations, and are much more willing to cede authority to those in power. Democrats, despite the discipline of individual campaign efforts, tend more toward anarchy than hierarchy. Historically, one result of this partisan difference is that the Republican establishment has tightly managed candidate selection at the presidential level. With extraordinary consistency, the party has crushed insurgent candidates and selected the next in line. Ronald Reagan and Bob Dole, for example, both had to wait until it was their turn.
