I am beginning to believe that the true issue here is political opportunism. On the one hand, we have two liberal Democrat mayors of two large California cities, Gavin Newsom and Antonio Villraigoza, (the former of which literally thumbed his nose at the state constitution that he was sworn to uphold in his office--but never mind that, right?), both of which are heterosexual males and strong supporters of same-sex marriage. Yet both of these men, had so little respect for this institution in their own personal lives that they decided to cheat on their wives.
And now of course we have Nevada's Sen. John Ensign, a conservative Republican who opposes same-sex marriage for whatever lofty reasons (a conservative Vegas paper still labeled him an upstanding citizen), yet did not respect said institution enough in his own personal life enough to refrain from cheating on his wife.
Newsom and Villaraigoza simply court (no pun intended) the gay vote, while Ensign courts those opposed to same-sex marriage, also for votes. All three men are hypocrites in their personal lives and self-seeking opportunists in their political lives. Ah, but now they want us to trust them with our votes!
