No communion for Obama supporters
It's down to one issue.
Voting for a pro-abortion politician when a plausible pro-life alternative exits constitutes material cooperation with intrinsic evil, and those Catholics who do so place themselves outside of the full communion of Christ's Church and under the judgment of divine law. Persons in this condition should not receive Holy Communion until and unless they are reconciled to God in the Sacrament of Penance, lest they eat and drink their own condemnation.
And here is another quote:
In fact, in this election, for the sake of argument, if the Republican candidate had been pro-abortion, and the Democratic candidate had been pro-life, everything that I wrote would have been exactly the same.
