"Election-year polls have shown Catholic support about evenly split between Kerry and President George W. Bush, with churchgoing Catholics favoring Bush and those who rarely attend Mass preferring Kerry. "
Catholicism is like Judiasm in some respects--there are cultural Catholics and there are religious Catholics. Those who are cultural Catholics (called A&P Catholics here--they only go to church for Ashes and Palms) tend to be very liberal socially. The religious Catholics hold strongly to pro-life views and tend to be more conservative.
From the perspective of many Evangelicals, it is wrong that there are so many Catholics who are so politically liberal that they deny major tenants of their faith. But from my experience, the more seriously religious Evangelical Protestants have ripped up their 'tares'. Their culture is so fervent that only the 'true believers' can tolerate attending. That is why many Evangelicals will look around their church and smugly, if quietly, say that 90% of the attendees are 'saved'. And they'd look at my church and wonder if even 10% were 'saved'.
If you ask a Catholic--a religious one; a cultural one wouldn't understand the question--how many in his church are saved, he'd probably answer, 'None, yet.' And he'd understand what Jesus meant by the parable of the wheat and the tares. He also wouldn't even think about identifying the tares, much less pulling them up.
I know I've gotten far from the political commentary that inspired this blog, but it's something I've noticed about Catholics. In our church, all are welcome. On the surface it might seem to a Protestant that the standards are held too low and all the riff-raff are allowed in. Seems to me that the standards of God are so high that from His perspective we're all grubbing around in the dirt.
