“claims” Is the perfunctory word.
But Obama doesn’t even “claim” to be pro life. And maybe Romney’s conversion is real. Isn’t it a good thing when people change to a more correcet viewpoint? And in any event, even if Romney was faking, I would guess it was his pro-choice stance that was a fake to get elected in MA, while his true inclinations were pro-life (based on his religion and family life), just like my assumption is that Obama has been pro-same sex marriage all along but was pretending to be against for political purposes.
