IRS Reviews Church's Status

I read today in the Washington Post the IRS is investigating All Saints Church in Pasadena, CA for an anti-Bush sermon the pastor gave. http://www.washingtonpost.com/wp-dyn/content/article/2005/11/18/AR2005111802501.html
I wonder if Comissioner Mark Everson plans on revoking the tax status of the Archdiocese of St. Louis after Archbishop Burke told his congregation to not vote for politicians who support abortion?
