Today, the United States Senate passed the United States-Peru Trade Promotion agreement by a vote of 77-18 . (The House of Representatives passed it in November.)
Notable is that the five sitting senators happen to be the same sitting senators who are running for president (Obama, Clinton, Dodd, Biden, and McCain). It is interesting that while four of them were at the same place today (the Democratic radio debate in Iowa), no one asked them about it.
It's also interesting that many of the 18 senators (all Democrats) who voted nay include the several of the more protectionist senators (e.g. Brown, Casey, Tester) elected from purple states last November, largely on the votes of anti-globalization Reagan Democrats.
It will be interesting to see how this protectionist thread (embodied by Edwards and Kuchinich at the presidential candidate level) plays out for the Democrats in 2008.
