Cardinal Dolan will deliver benediction at RNC Convention on night Romney accepts nomination.

WASHINGTON — Mitt Romney is going to get a big televised blessing from Timothy Cardinal Dolan, who will deliver the benediction at the Republican National Convention on the night the presidential contender accepts the party’s nomination.

Romney, a Mormon who is trying to reach out to blue-collar and Catholic voters in swing states, announced the news in an interview on a Catholic radio network yesterday.

A Dolan spokesman insisted the cardinal’s appearance next Thursday in Tampa will not be an endorsement.

“This is not a partisan appearance. This is simply to do what a priest should do, which is to pray,” Joseph Zwilling, Dolan’s spokesman, told The Post. “He’s going to pray. He’s not going to give a convention speech.”
