How can the writer and sponser of the Defense of Marriage Act?

Question

Run for president for a party who's platform includes repeal of said law.

Answer 1

Like it matters.  This is Bob Barr, after all.  No one will see his hypocrisy, and he'll still lose.

And they won't see his hypocrisy, because no one is paying any attention to that fool (except for maybe you--but only to point out his hypocrisy).
