Via The Cloakroom:
1. Libertarians vs. social conservatives
These two GOP strains have never gotten along with each other. One group says government should stay out of people’s personal lives while the other tries to impose its own morality on others.
2. Right wing populists vs. the pro-business crowd
Despite campaign rhetoric, pro-business Republicans are usually just fine with government subsidies, liberal immigration policies, and bailouts — as long as they help keep the profits flowing. But the populist strain in the party sees big business as no better than big government.
3. Deficit reduction hawks vs. small government activists
Though it would seem these two groups have a lot in common, real deficit hawks recognize we must raise taxes along with cutting spending to get the country out from under the debt burden. But the small government fanatics are against all tax increases for any reason.
