If you don't have many issues to attack the President on, attack his ads.
Update:
Compare this strategy with the mthods used by France, Germany, the UN, et al, to tie the hands of America before we went into Iraq. They knew they didn't have the power to actually stop us, so they focused all their energy on harrassing us with accusations of unfairness and unilateralism. If you can't win, change the game.
And if you have a shallow faith, spend most of your time blaming gays for problems within the institution of marriage.
Gays should not be blamed for problems with the institution of marriage. Married couples are the primary ones to blame, for not taking it seriously enough; to the point where it is now so weak of an institution, that the gay agenda is having an easy time tearing into it.
I don't think anyone in their right mind would accuse gays of ruining marriage- Hetero couples have done enough damage to it.
Sadly, as a consequence, it seems that the gay agenda will deliver the final blow to this now crippled institution. Therefore, society in this nation as a whole, will share responsibility for it's demise.
