(Editor's Note: Biden dropped out of the presidential race for the Democratic nomination, following a poor showing in the Iowa caucuses on Jan. 3, 2008, where he got only about 2 percent of the delegates.)
He opposes deporting the 14 million illegal immigrants already in the U.S. He proposes that background checks weed out the criminals to send back and provide for pathway towards "earned citizenship" for the rest. He views the U.S.-Mexican border not only as a gateway for illegal immigrants, but for drug trafficking as well. He strengthened border patrol and a shorter fence than the one voted on in September 2006 would help to ease future immigration problems.
