Depends on what types, the more traditional minded Catholics will be there with the Evangelicals to also do the heavy lifting. The other types are CINOS, whom you do need to worry.
The other types represent a majority of your church. Your church makes noise, but it's members don't walk the faith they claim. Obama is not an idiot. He knows the only ones he won't get because of his positions on contraception, abortificents and now homosexual marriage are Born Again Christians. He never had anything close to a majority of our votes from the get go, so he hasn't lost anything.
Look at the states that have some form of legalized homosexual unions they are on the west coast, northeast, and some in the midwest. Most of these states have large RC populations. They are definitely not majority Born Again Christian areas.
