http://www.guardian.co.uk/world/2009/apr/14/vatican-vetoes-obama-nominees-abortionThe Vatican has vetoed three of Barack Obama's potential nominees as US ambassador amid a growing dispute between the White House and the Roman Catholic church over the new administration's support for abortion rights and the lifting of a ban on stem cell research.
Vatican sources told Italy's Il Giornale newspaper that among those rejected were Caroline Kennedy and two other Roman Catholics who were unacceptable to the pope because they have publicly stood against church dogma.
To give one an idea of how extremist the Church hierarchy now is, look at why they rejected another candidate:
The Vatican also rejected another potential nominee, Douglas Kmiec, a professor of constitutional law at Pepperdine University and former head of the office of legal counsel for Presidents Ronald Reagan and George Bush Sr. Kmiec, a Republican who endorsed Obama during the last election campaign, has said that Catholics who support the right to abortion need not follow the church's admonition to vote for an anti-abortion presidential candidate.
So that guy is not necessarily pro-choice (since he worked for Reagan & Bush he may be pro-life), but since he defended other Catholics who voted for Obama (or even Kerry) he has been deemed unacceptable.
I also just heard a report on NPR about this, so this is pretty sure to be true. The Vatican denies it, but that's only a technicality: they have essentially rejected these candidates.
