The Washington Post:
Is the WTO one of Trump's `big quagmire deals'? here's what's at stake
28 February 2017
Recent research by Paola Conconi, Maurizio Zanardi and their co-authors finds U.S. presidential elections tend to influence the timing of WTO dispute filings, especially those with economic interests in key electoral (“swing”) states. But if domestic politics drove the filing of those cases and winning them would mainly help a political opponent, incoming presidents may choose to drop them entirely and focus on their own priorities.
