Insofar as the political dynamics are concerned, conservatives and libertarians are generally fearful of democracy. That is because, in principle, there is essentially no constraint on the ability of the majority to take from the minority and reward themselves in a pure democracy. The founding fathers very much shared this concern and intentionally enacted numerous restraints on the majority to protect the rights of the minority to their wealth. Among these are the federal system, with relatively strong states and a weak national legislature, as compared to parliamentary systems, and a Senate where small, sparsely populated states, per capita, have more influence than large, populous states; a written constitution with strong protection for property rights; and an Electoral College instead of election of the president by pure popular vote.

They vote in lower percentages than the well-to-do and often suffer from policies to reduce their political influence, such as onerous voter registration requirements, demands for government identification at the polls and long waiting times to vote on Election Day.

On the other hand, research by the political scientist Martin Gilens in his book Affluence and Influence: Economic Inequality and Political Power in America shows that the wealthy tend to be more liberal than the Republican Party on social issues. By and large, the wealthy are not religious, favor abortion rights and support gay rights. The best hope for liberals in the future may be to emphasize social issues, which split the Republican Party between the interests of the wealthy and those of religious and social conservatives who dominate primary elections.
