Senate Republicans are weighing whether to use the limited legislative calendar before the Nov. 3 election to address voters' cost-of-living concerns, even as rising gas prices, the ongoing Iran war and worsening midterm polling threaten their majority. House Republicans have already left Washington until after the election.

The contrast between Americans' economic difficulties and the Senate's relatively low-stakes agenda has prompted anxious Republican lawmakers to question whether they can respond effectively before voting begins.
