During the initial debate last year, some of the biggest opponents of the TPP were Democratic U.S. senators, who did not support President Barack Obama’s efforts to secure the agreement with 11 other countries. But the senators’ opposition to the TPP isn’t consistent with the views of rank-and-file Democrats. Identical majorities of Democrats and independents have viewed foreign trade as an economic opportunity over the last two years: 61% in 2015 and 63% in the latest poll.

Meanwhile, about half of Republicans view foreign trade as an opportunity — similar to their views since 2013. Republicans were a bit more enthusiastic about foreign trade during the first half of George W. Bush’s presidency than during the second half of his presidency and now under Obama. They were the party group most likely to view foreign trade as an opportunity until 2012. Although Bush initiated the framework of the TPP agreement that Obama has brought to Congress, rank-and-file Republicans may have lost enthusiasm for foreign trade under the leadership of a Democratic president.
