Good better late than never. It’s possible that the example of 50 other bishops, and maybe a few words from his flock, made him think again.
It must be said that the bishops have spoken out this election season as they have never done before. Even the best of them have generally grown quiet this close to an election. But they obviously see that this is absolutely critical this time.
Just as one example, the so-called "Freedom of Choice Act" could spell the end of Catholic hospitals and Catholic Charities. And then the "Human Rights Commissions" along the lines of the ones in Canada that have been levying hefty fines against priests and ministers that speak out against homosexual 'marriage', etc.
