I'm a homo and no matter what the dems could tell me about marriage my vote would go to Romney/Ryan this cycle. Once gay marriage is legal in the whole country dems wouldn't be able to keep the homo voting bloc, which is why they will never act on it (and blame republican outcry as their reason not to force the issue). Many homos are waking up to the fact they end up as DINKs later in life (double income no kids) and with 'progressive' taxes from the left why would I support an administration not only inactive on social issues but also increasing my taxation? Its pretty plain and simple no?
I love this post for so many different reasons.
Though be quite fair, LGBT Americans are not a monolithic Democratic voting bloc. The GOP took somewhere around 35% or so of LGBT voters in 2010, which is probably better than the GOP does among conservative evangelical fundamentalist blacks.
