During his long tenure in the Senate, Joe Biden of Delaware has compiled a mixed record on votes affecting our freedom to participate in the global economy. The record of the Democratic vice-presidential hopeful is more pro-trade than Barack Obama’s but much less so than John McCain’s.

According to our “Trade Vote Records” feature on the Cato trade center web site, Biden has voted in favor of lower trade barriers on 24 out of 48 votes in the past 15 years. On trade-distorting subsidies, such as farm price supports, he has voted for lower subsidies on only 3 of 11 votes. Since Obama joined the Senate in 2005, he has voted for lower barriers 36 percent of the time and for lower subsidies 0 percent. John McCain has voted for lower barriers on 88 percent of votes and for lower subsidies on 80 percent.

Here are the highlights and lowlights of Biden’s voting record on trade:

On the positive side from a free trade perspective, he voted consistently to maintain normal trade relations with China, including permanent NTR in 2000; for the North American Free Trade Agreement with Canada and Mexico in 1993; for the Uruguay Round Agreements Act in 1994; for the Freedom to Farm Act in 1996; for fast-track trade promotion authority in 1998; to defund enforcement of the travel ban to Cuba; to cut sugar production subsidies; and in favor of the Morocco and Australian free trade agreements in 2004.

On the negative side for those who support the freedom to trade, Biden voted for steel import quotas in 1999; for the 2002 and 2008 protective and subsidy laden farm bills; against trade promotion authority in 2002; against the Chile, Singapore, Oman, and Dominican Republic-Central American FTAs; in favor of the Byrd amendment directing anti-dumping booty to complaining companies; in favor of imposing steep tariffs on imports from China to force changes in that country’s currency regime; and in favor of screening of 100 percent income shipping containers by 2012.

For a senator who prides himself on his foreign policy experience, Biden’s record shows great ambivalence about American participation in the global economy.
