Larry Summers echoes my interpretation of the electoral impact on trade policy:
The challenge for trade policy in the next two years will be more to resist protection than to further liberalisation, since both parties want to respond to the economically anxious middle class that disproportionately projects its anxieties on trade agreements. [FT]
On the other hand, Dan Griswold claims that the partisan shift matters:
The election means that the president’s trade agenda has come to a screeching halt. [AFP]
What? I must have missed Bush’s swiftly speeding trade agenda! The election is a tap on the brakes of a vehicle was coming to a rolling stop anyway.
