Mr. Lebowski above hit it on the head when he properly identified them as the TEA Party. The group was founded around one concept - "Taxed Enough Already". It's an acronym that defines their overall goals.
Arguably, as others have stated, the TEA Party may have both social conservatives and social liberals, because it's fiscal conservatism that is their center piece. Whether or not that's the reality would likely depend on your local group, as there's not really a true national TEA Party.
