Its the stock disingenous right wing argument, (Oh you'll vote for Obama but not Mia Love?) which isnt a shock considering Greenwald started out a Ron Paul stan.That's a totally nonsensical line of argument. Being in favour of more women running for office doesn't mean you automatically support all women in every race, particularly against people you may already consider an ally.
