There is a bill now pending in Congress, S.1925, "To Reauthorize the Violence Against Women Act of 1994", which primarily deals with that topic, but also seeks to create authority for Indian tribal courts to prosecute non-Indians for domestic violence, and then sneaks in the following:
"Section 1008. REMOVAL OF DRUNK DRIVERS
(a) In General: Section 101(a)(43)(F) of the Immigration and Nationality Act (8 U.S.C. 1101(a)(43)(F) is amended by striking "for which the term of imprisonment" and inserting "including a third drunk driving conviction, regardless of the States in which the convictions occurred or whether the offenses are classified as misdemeanors or felonies under State or Federal law, for which the term of imprisonment is"
and then another provision making that effective immediately on the date
of the amendment.
Thus anyone who got a third misdemeanor DWI, with one year imprisonment suspended, would have an aggravated felony, notwithstanding Leocal. This bill was reported out of the Senate Judiciary committee on February 7, 2012.
