Well, Catholics who do not attend Mass on Sunday are not really Catholics anymore. It is more accurate to refer to thenm as former Catholics or people who were “born Catholic.” Faithful Catholics , who do attend Sunday Mass, voted overwhelminhgly against Obama, as they did in 2008. These faithful Catholics would have heard or read the bishops’ statements.
I would suspect that a majority of the Catholics who voted socialist came from south of the border.
Please document your excuse. I know for a fact that my liberal 'social justice' Catholic in-laws attend mass routinely, some send their children to Catholic schools and spend nearly all their free time involved in some sort of Catholic arrangements. Some of these people spend more time in a Catholic owned property than they do at their own homes. This excuse of calling people 'cinos' claiming they do not attend weekly mass is bunk.
It was Catholics that wrote Obamacare along with a few other liberals. Isn't Supreme Roberts said to be a practicing Catholic. Thankfully for the rest of US God does not need mere mortals to keep His record books.
