The 2018 midterm elections have largely been characterized as a test of the traditional two-party political system in America. More specifically, this election year will largely be viewed as a test of the viability of the Republican Party, and President Trump. There are 34 Senate seats up for reelection this November. In the House, all 435 seats will be up for reelection. Currently, Republicans have a majority in the Senate by just two seats, making this year’s election cycle particularly compelling because of this extremely narrow majority. Over in the House of Representatives, the Republican Party holds the majority with 239 seats. Those who win this November with be part of the 116th Congress which will begin in January 2019.
