In the United States, the Tuesday following the first Monday in November is Election Day. This year’s is known as a midterm election, because it occurs halfway into the President’s four-year term. Midterm elections are important because all 435 seats in the House of Representative are up for grabs, and this year, 37 of the 100 Senate seats will also be determined. (In addition, there are elections for governor in 37 U.S. states this year, as well as many state and local elections.)
Before the election, in the U.S. House of Representatives, the Democratic party held 256 seats and the Republican party held 179. In the Senate, the Democrats held 59 seats and the Republicans held 41 seats. For the Republicans to gain the majority (one more than half) of the seats in both houses of Congress: How many more House of Representative seats would they need than they currently hold? How many more Senate seats would they need than they currently hold?
