Ol' Doom N' Gloom Janet is cherry-picking. Here's the full accounting of where Biden stands on abortion:

    * No public funding for abortion; it imposes a view. (Apr 2007)
    * Supports partial-birth abortion ban, but not undoing Roe. (Apr 2007)
    * Accepts Catholic church view that life begins at conception. (Apr 2007)
    * Nominees should agree on constitutional right to privacy. (Apr 2007)
    * Voted NO on defining unborn child as eligible for SCHIP. (Mar 2008)
    * Voted NO on prohibiting minors crossing state lines for abortion. (Mar 2008)
    * Voted YES on expanding research to more embryonic stem cell lines. (Apr 2007)
    * Voted NO on notifying parents of minors who get out-of-state abortions. (Jul 2006)
    * Voted YES on $100M to reduce teen pregnancy by education & contraceptives. (Mar 2005)
    * Voted NO on criminal penalty for harming unborn fetus during other crime. (Mar 2004)
    * Voted NO on maintaining ban on Military Base Abortions. (Jun 2000)
    * Voted YES on banning partial birth abortions. (Oct 1999)
    * Voted NO on banning human cloning. (Feb 1998)
    * Rated 36% by NARAL, indicating a mixed voting record on abortion. (Dec 2003)
    * Expand embryonic stem cell research. (Jun 2004)
    * Rated 0% by the NRLC, indicating a pro-choice stance. (Dec 2006)
    * Ensure access to and funding for contraception. (Feb 2007)

Like I said, a mixed bag. Also noted from the same site:

Religion informs my values; my reason dictates outcomes.
# Religious affiliation: Catholic. (Nov 2000)
# Rated 100% by the AU, indicating support of church-state separation. (Dec 2006)

It is possible to have a religious affiliation and NOT try to cram it down everyone else's throat. Are you trying to resurrect the anti-Catholic BS they tried to use against JFK?
