HA!! I don't think so. :) Your Church is "officially" on the right side of many moral issues, but Catholics, at least in this country, are one of liberalism's best buddies. Your Church voted for pro-abortion Gore in 2000, and you helped to hand Congress over to the Democrats in 2006. And over the last 9 presidential elections, the record of the Church is just over 50-50 in voting for pro-aborts vs. pro-lifers. Even when Catholics supported Bush over Kerry, it was only by 5 points nationwide. No such statistics apply to evangelicals. If Catholics voted in accordance with what you say is Catholicism, there wouldn't be any liberals.
Rhode Island and Massachusetts are the two biggest Catholic states per capita in the country. Not only do pro-abortionists OWN those states, but Mass. is the state that passed the law recognizing the wonder and splendor of gay marriage. If I was a liberal I would immediately go after the Catholic vote because I would think I could get it. I wouldn't bother with the evangelicals. Here is an opinion piece from the New York Sun that lays out some facts:

And let's not forget BD's point, the position of the Church is to side with liberalism and surrender in Iraq, letting the terrorists take over. Still further we can add that many Catholic Churches are acting as sanctuaries for illegal aliens. In the southwest, at least, the liberal Catholic position is for open borders. You really have no claim to fidelity to conservatism.
The liberalism of the RCC is probably rooted in it's historic relation to the state and the underlying teaching that members should subordinate their understanding to that of the greater institution ie., the church. Liberalism always seeks to subordinate the individual in the name of the group. Conservatism seeks to free the individual and only have the state exercise it's power to protect those freedoms.
