As long as the democrats can count on winning the majority of Catholic voters for their pro-abortion, pro-homosexual marriage and anti-God party, then they will be doing everything in their power to increase the number of Catholic voters.
Quantitatively, the Democrats get more Protestant votes than Catholic votes. We both have a lot of work to do. You should be at least as concerned about cleaning up the bigger Protestant mess as you are with the wayward minority of Catholics.
If it is percentages you are concerned with you should spend some time with blacks, Asians, Jews, women, Hispanics, and union members, all whom voted for Obama in greater percentages than the 25% if Catholics who did. It feels to me like your agenda is not so much pro-GOP as it is anti-Catholic.
