Custom House, maintained by Ben Muse of Alaska, has been doing a nice series of posts on the trade positions of candidates in multiple (mostly Senatorial) congressional races in the US. It is worth taking a glance if you are interested where candidates in some of the key races stand. For the US presidential candidates' positions on trade with Northeast Asia, please refer back to my recent post on this topic.
Also, don't miss out on Ben's Korea-US FTA blog as well. It is a great one-stop-shop of information on this FTA and its developments.
