By David Morgan, Richard Cowan and Andy Sullivan WASHINGTON (Reuters) -Even before the last vote on U.S. President Donald Trump's sweeping tax-cut and spending bill was counted, Republicans and Democrats in Congress began gaming out how to use it to gain an edge in the 2026 midterm elections.

President Donald Trump signs $3.3 trillion tax bill that extends 2017 tax cuts, raises debt limit by $5 trillion, rescinds Biden green energy credits, and adds Medicaid work requirements.
