You can stop right there, as that represents the majority of Catholics in the US.
Sadly, yes, 52% of voters who self-identify as Catholics voted for Obama. I spoke to several of them in my Parish after the election. They truly believed that Obama wasn’t that pro-abortion, because they’d heard Catholics publicly supporting him, but since they believe Republicans hate the poor, anyway, they believed they had to vote for Obama. They, like too many other American voters, got their news about Obama from the MSM, which did all it could to cover up just how liberal he actually is. But remember, this is MA, where union dominated blue collar ‘Catholics’ voted every 6 years for Teddy the Swimmer.
