Yes, it will be good if even greater number of Catholics dropped their illogical support for the "party of abortion and evil and liberalism". However, on that score, I would invite the Protestants, if they truly reject abortion and liberalism, to make the GOP into a party that puts an end to abortion and liberalism in more places than just their platform. Every time the GOP gets to power they quickly forget all about being supposedly pro-life. Every time they have a real opportunity to win an election, they make room for someone without a clear pro-life record and hush down their pro-life rhetoric in order not to scare away the mythical "undecided voter"; in the meanwhile the voter who is already decided, and instructed by their religion to vote pro-life sees no credible pro-life candidate. Something similar occurs with liberalism: GOP does a lot of chest-beating about restoring capitalism in America, then they nominate "tax collectors for the welfare state": classic examples are Romney and his wobbly pro-life record (and, what should be clearly unacceptable to any Christian, Mormonism) and Dole with his career in the US Senate making tax deals. Every time the GOP nominates someone lately, the Tea Party has to fight not the Democrats but the GOP to get a true conservative in the race. That is the Protestant leadership in the GOP: cowards and weasels. If you want to attract a greater number of Catholics, become attractive.
Yes, I have personal opinions. I also argument them. If you don't agree with them, argue back; that is what the Free Republic is for.
What you can’t escape with your anti-Americanism, is that Protestantism leads to conservatism, and Catholicism leads to liberalism, that is why the rewriting of our Immigration laws to import democrats, was such a deliberate strategy of the left, to gain power over America, Catholics=liberalism=the end of the original Americans of 1776.
