The head of the diocese of Providence, R.I., said he left the Democratic Party for the GOP after witnessing the pro-abortion, pro-same sex marriage stance of the party at the 2012 Democratic National Convention.
For Catholic Bishop Thomas Tobin, that was his "a-ha moment." He had been a registered Democrat since 1969.
"[I]t was just awful,” Tobin said of the DNC on Tuesday before a meeting of the Rhody Young Republicans in Providence.
Tobin, 65, said he is unwilling to be "associated structurally with that group, in terms of abortion and NARAL and Planned Parenthood and [the] same-sex marriage agenda and cultural destruction I saw going on," WPRI-TV reports. "I just couldn't do it anymore."
The bishop has changed his party registration to Republican, though the registration itself doesn't mean much to him.
Tobin said he was "profoundly disappointed" that many Catholic politicians in the state of Rhode Island "abandoned ship" on the issue of gay marriage.
"This was a critical issue and they let us down," he added.
