The second myth is that Republican leadership wants to end abortion. That's not true in the least.
Obviously the Christian Conservatives are a huge portion of the voting bloc of the Republican party. The biggest Christian issue of the moment is abortion. If abortion becomes illegal the fight over it will die down considerably (though obviously it won't end). But once that happens, Christians will have to focus on other Christian beliefs.
And yes, while I realize a LOT of Christians won't change teams just out of stubbornness, some will, because frankly, other than abortion, the Left satisfies the White Christian guilt of middle America than the Right. Other than abortion, name another 'Christian' trait the right espouses? Feed the hungry? Mercy for the imprisoned? Swords into Plowshares? Hell, the Beattitudes are practically a Democratic Party Platform.
Jesus was a liberal progressive.
