President Obama's endorsement of gay marriage undoubtedly reflects a personal evolution in his thinking, as he's said.
But his decision also reflects a hard-headed acknowledgement of the changing nature of the Democratic electoral coalition. Indeed, historians may someday view Obama's announcement Wednesday as a milestone in the evolution of his party's political strategy, because it shows the president and his campaign team are increasingly comfortable responding to the actual coalition that elects Democrats today -- not the one that many in the party remember from their youth.
The article asserts that Obama's decision will further drive the dems away from lower class whites and older voters - who might otherwise be inclined to support them on economic issues, and accelerate their move into more socially liberal terrain. But it will appeal to who's turned out to be their biggest base of support in the last few elections: younger voters, minorities and educated white collar liberals, especially women. As a political move, this seems wise to me, at least in the long term. This coalition is looking to dominate, especially once the baby boomers and their "angry white males" start dying off.
