Something simple I've been pondering. On the basic political spectrum, conservatives are for economic liberty, but want government involved in social matters. Liberals want social liberty, but want the government involved in economic matter.
The saying that liberals want more social liberty and less economic liberty on
every issue (and the reverse for conservatives) is oversimplistic.
It is true in general, but there are many exceptions. Guns and tobacco are the exceptions in the social realm, and in the economic realm, conservatives tend to favor more government in the areas of military spending, spending on NASA, and gambling and prostitution.
