The few people who pay attention to U.S. foreign policy usually remember Elliot Abrams for pleading guilty to lying to Congress about the Iran-Contra scandal, or for helping to cover up the El Mozote massacre of at least 800 unarmed peasants by the Salvadoran government in 1981. (He collaborated on this with Thomas Enders.)
Vice presidential candidates can be fun to discuss as long as we remember that they matter very little. However, this comes on top of Mitt Romney having very far right advisers on Latin America, such as Ray Walser. With Romney, as with George W. Bush, we would very likely see a push--though, to be fair, also pushback, a la Thomas Shannon--by Cold Warriors to become influential once again, with the goal of returning U.S. policy largely to a 1980s mindset. If Romney is elected, look for some appointment battles.
