“Democrats won control of both chambers of Congress, a majority of governorships and more in a massive midterm rebuke of President Trump. In doing so, they pulled off a feat that has bedeviled them for years: uniting around a message—affordability,” the Wall Street Journal reports.“The party mostly managed to keep the spotlight on the economy as candidates drove home that Trump’s policies are hurting pocket books. They coalesced around this message, even as a fight for the party’s direction continues to boil. Centrist and far-left candidates alike drilled down on the economy, and largely avoided being drawn into culture wars that have cost Democrats in recent elections.”
