Trade war threatens to roil 2020 race as Republicans complain about the tariffs Trump loves

President Trump’s aggressive trade policies are running headlong into his campaign for reelection.

As Trump prepares to run on the economy, his threat to increase tariffs on imports from China has sent the stock market diving and undercut a stretch of positive economic news. U.S. farmers and exporters, already bearing the brunt of China’s retaliatory tariffs, now face the prospect of an escalated trade war in which states that Trump needs to win reelection will be in the crosshairs.

The trade war has also exposed a rift inside the White House and among the president’s allies — with some officials pushing for a quick resolution to calm the markets ahead of 2020, and others warning the president that a weak deal with China could leave him politically vulnerable.
