When it comes to political battles, conservatives are at a natural disadvantage. By the very essence of their ideologies, liberalism is far more active than conservatism. For almost every issue, liberalism easily passes the “we have to do something” test.
As proponents of a powerful and active government, liberal solutions are visible and easily traceable. To solve a problem they might propose a new government agency, a new government program, impose new government requirements, or bills to outlaw whatever is perceived to cause the problem. With any of these options, liberal politicians can easily go to their constituents and show a one-step link between the problem and proposed solution.
