Here's the lay of the land. The Senate is currently divided between 51 Republicans and 49 Democrats (including two Independents who caucus with the Democrats). A change of two seats in favor of the Democrats will give Democrats control of the Senate under the leadership of Chuck Schumer of New York.
Of the 100 Senate seats, 35 are up for election in 2018. Those 35 Senate seats are currently divided among 24 Democrats, two Independents who caucus with Democrats and nine Republicans. Simply put, the Democrats have more turf to defend and potentially more to lose.
