maybe most christians do not base their vote on the abortion issue alone...if at all.
No maybe about it. (

This is a sad truth....and that's why the abortion mills have been busy ever since 1973. This Catholic though knows the Church regards abortion as well as embryonic stem cell research as "intrinsically evil", a sin against the Commandment of God, "thou shalt not kill." As for Obama, he heartlessly voted to deny health care for babies born alive who survived an abortion. That's evil and on that one issue alone, Christians should not vote for him. Human life is sacred and direct attacks on innocent life are never morally acceptable.
I respect your opinion about marriage as a whole but why is it that the GOP has to try to CHANGE state constitutions to deny CIVIL marriage?
If you'll check, I think you'll find it was not Republicans, but Democrats in states such as Vermont, Massachusetts, New Hampshire and California who demanded same-sex civil unions which grant the same legal benefits as civil marriage.
In any case the civil marriage issue is mostly benign this election.
Last month, in California we learned civil unions is not enough...the California Supreme Court decided to redefine marriage to include homosexuals. This means starting June 17, homosexuals from all over the country can go to California, get married, and go back to their home state...and guess what...file a federal lawsuit demanding that their state recognize them as married.
Oh ya, this could very well force the candidate's position on homosexual "marriage".
It's mainly GOP conservatives who recognize that it takes a state constitutional amendment defining the institution of marriage as between a man and a woman as the only way to keep traditional marriage, traditional.
