(Bloomberg) — Terms of Trade is a daily newsletter that untangles a world embroiled in trade wars. Sign up here. For now, the five senators running for president are staying on the sidelines of the push to rewrite the North American Free Trade Agreement, but they’ll have to vote on the new treaty by next year.Senators Elizabeth Warren and Bernie Sanders have long argued against President Donald Trump’s proposed revision of Nafta, known as the U.S.-Mexico-Canada Agreement, arguing it should have stronger labor and environmental protections.But in the day since House Speaker Nancy Pelosi unveiled a bipartisan compromise backed by the AFL-CIO labor federation that includes some of those measures, the presidential candidates have kept quiet.So has former Vice President Joe Biden, who has taken criticism from Sanders for his support of the original free trade deal in the 1990s. Senators Amy Klobuchar and Cory Booker, who both called for changes to the deal earlier this year, also haven’t spoken out.Only Senator Michael Bennet responded to a request for comment from Bloomberg News, noting that he has called for a “modernized trade agreement” and an end to Trump’s “reckless and unstrategic approach to trade.”“I look forward to reviewing the details of yesterday’s announced deal,” Bennet said. “I’m hopeful that this trade agreement can be a positive step in that direction.”Majority Leader Mitch McConnell has said the Senate will vote on the trade deal after an impeachment trial is finished, sometime in early 2020.(Michael Bloomberg is also seeking the Democratic presidential nomination.
