You're presuming people can actually find a party that doesn't have politicians who are homosexual or have homosexual children.
So no, I don't think that prediction will come true.
You need to keep up on my commentaries. Turned out ~ actually this has happened several times so, let’s say it turns out that the American people will not, in general, vote for Republicans when they feel the party is being overrun with gay politicians. in 2006 we lost big time over that particular issue.
