No but the Due Process Clause is included in the Fifth and Fourteenth Amendments, and the Equal Protection Clause is included in the Fourteenth. Federal Courts used those to justify overturning laws against interracial marriage and I assume they're using the same clauses to rule on same sex marriage.
It's true they did, but they didn't have the authority. They were making it up. We need to reclaim the plain meaning of the Constitution if we want to reclaim the country. Banning interracial marriage may be daft and ultimately undefinable, but saner states are free to attract citizens who don't want daft laws on marriage—that's our defense against stupid laws, not Federal ambulance chasing. Hard cases make bad law, and ultimately destroy the Constitution.
If we want a government that's less corrupt, we have to play by our own rules.
