Romney appointed 2 judges in Massachusetts that were members of homosexual rights groups. Voila! Homosexual "marriage" via the courts in Mass. Think SCOTUS. You want him picking nominees? CONSERVATIVES do not.
Obama is far, far worse than Romney. Also, if Obama wins, this election will be seen as an endorsement of Obama policy.
If Romney wins? Romney can be held to his promises and thrown out if he breaks any of them.
If Obama is reelected our Country is lost, it is that simple.
