Well, you have me convinced. That damn Newt converted to Catholicism, the bastard.
I have no problem with religious conversions as such so long as they imply either contemplation (as in "Judaism is richer than what I grew up with"), a change in personal life for the better ("I became a Mormon and quit drinking" or "I became a Muslim and gave up racism" ), confirmation of the stronger faith of of a spouse ("My wife convinced me that Catholicism would strengthen our marriage"). When it reeks of opportunism it is suspect.
