No communion for Obama supporters

In South Carolina Roman Catholic priest, Rev. Jay Scott Newman made a letter and distributed to churchgoers at St. Mary Catholic Church saying that churchgoers who voted for Barack Obama should abstain from receiving Holy Communion because supports abortion. He also said, “Our nation has chosen for its chief executive the most radical pro-abortion politician ever to serve in the United States Senate or to run for president.” "Voting for a pro-abortion politician when a plausible pro-life alternative exists 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."

I am against abortion and not Obama supporter. This policy is hard to argue because Catholics have their own doctrines. It was people’s choice and prerogative. We are all sinners. Yet, God still loves us. What do you think about this Catholic policy?
