The daughter of 2008 GOP presidential nominee John McCain has stood apart from many Republicans by standing up very publicly for LGBT equality.
But that doesn't mean she's ready to vote for Barack Obama because he became the first sitting US president in history to endorse gay marriage.
McCain tells Michelangelo Signorile on his radio show: 'I'm not impressed with Obama going on TV and saying, 'I have gay friends and I think they should get married.' That to me is the same thing as saying, 'I have black friends and they should get married but I’m not actually going to pass legislation that interracial marriage should happen.' If you put it in those terms it’s a completely different situation.'
Obama's support among LGBT voters has soared since he endorsed gay marriage. But McCain believes they should not be 'one-issue voters.'
' ... As far as I’m concerned, he’s not doing enough for the gay community and it's not enough to sway me,' she says. 'I'm glad it's okay with you guys but it's not enough for me. I know lots of gay people that are voting for Romney, because I think in America, people aren’t one-issue voters.'
