Sen. Obama tanked with Catholics in Pennsylvania, and losing Catholics nationally would be a definite burden to carry into the general election. I found one glint of a silver lining for Sen. Obama: despite his struggles, he has shown himself able to win in heavily Catholic states.

There are 12 states in which white Catholics make up at least 25% of the population. Sen. Obama has won six (Connecticut, Louisiana, Maine, North Dakota, Wisconsin and Vermont); Sen. Clinton has won six (Massachusetts, New Hampshire, New Jersey, Pennsylvania and Rhode Island).
