As the parties stand today, seems impossible to be both Catholic and a Democrat. But tomorrow, if some republicans have their way it may be equally impossible to vote for some of them. (I am a republican Catholic). In fact I would be hard put to vote for president Bush again given his approval of the morning after pill.
But what then? We are obligated, as Catholics to vote. As Catholics we may never choose the lesser evil but only the greater good. And that is becoming more and more of a problem as the secular world even in conservative politics becomes less in line with the same morals as many religions have.
It is scary.
As a registered Independent, I have had this discussion many times with Republicans who routinely assert that I should vote for Republicans because they aren't as bad as Democrats...in other words, they'll still take the country to hell in a handbasket, only they'll do it more slowly than the Dems would.
And they expect my vote for that. In good conscience, though, I can only cast a vote that will reflect the Lord's will as I understand it; I must vote for the candidate who would make my world most consistent with how the world is supposed to be.
Jeremiah was commissioned to spend a lifetime preaching repentance to a nation who wouldn't listen...and he knew they wouldn't listen...yet disobedience was never an option. Likewise, you and I must still vote for the right thing, even though achieving it may be politically impossible.
My advice is, if you have to write in the name of someone you trust, do so, and consider your duty well done. For this attitude, we will probably both get flamed.
