Could the US survive and prosper without liberals? Could the US survive and prosper without conservatives?

If you look at the track records of either political "ideology", liberalism has led America into more unconstitutional reforms and policies. It has led to the rise of anti-American groups and philosophies as well, like Marxism, Communism, Multiculturalism, et al. which all serve to undermine the intrinsic and singular identity of America as a whole and subvert it into a confused nation of undemocratic and non-free environments. Clical conservatism as it is defined and originally designed is the true path of the American Constitutional Republic. All the Founding Fathers understood this.
