Funny that condemning
both parties is liberal in your view. . . .
I have never claimed to be centrist. I’m rather too conservative, by my definition of conservative, to feel much enthusiasm about any form of American politics

. But that’s irrelevant. Your remark is an indefensible ad hominem. Deal with the issues instead of speculating about the supposedly dishonest motives of people with whom you disagree.
There are plenty of wealthy people in the Democratic Party. But the Republican Party appeals to people’s desire for great wealth without accountability. That is corrupt.
Ad hominem again. I don’t hate wealthy people. I just don’t believe that being wealthy is a great moral achievement that should be rewarded by society.
You’re confusing intrinsic and grave evils (see the blog
“Catholic Moral Theology”). It’s true that there are two clear points where the Democratic Party’s platform contradicts Catholic doctrine, and no equally clear points in the case of the Republicans. But there are numerous points–nearly everything
except for abortion and same-sex marriage–where the policies advocated by the Republican Party cannot be reconciled with Catholic teaching. The fact that these conflicts have to do with how you apply general principles to the specific situation of 21st-century America doesn’t make them any less grave, or the Republican Party any less corrupt. On issue after issue the Republicans take stances that cater to fear, nationalistic arrogance of the worst kind, and greed. Catholic Republicans pay lip service to the concept of the “common good” while endorsing policies that cannot be reconciled with Catholic teaching on the common good, given all the other circumstances.
The death penalty, which you addressed in the early part of your post, is a good example. Catholicism teaches that abortion is always wrong, while the death penalty may be justified under narrow circumstances. But those circumstances clearly don’t apply in the U.S. The way the death penalty is applied routinely results in the death of people about whose guilt there is considerable no doubt; cannot be shown to be necessary to defend the innocent; and perpetuates racial and class injustice in this country in a literally lethal and toxic manner. That makes the death penalty a very great evil. The fact that prudential reasoning has to be used to get to this conclusion doesn’t make the issue any less important.
