"As other candidates attack him for being too soft on unauthorized
immigration, Republican presidential candidate Newt Gingrich signed a
pledge on Thursday to build a double fence along the entirety of the
southern border of the United States. The former Speaker of the House promised in the Americans for Border
Security pledge to construct a complete double border fence between the
United States and Mexico by the end of 2013, should he become president.
Only one other GOP presidential candidate, Rep. Michele Bachmann
(R-Minn.), has signed the pledge so far." - HuffPo, Dec. 1, 2011.
