Half of Americans believe that Republicans will maintain control of the House in the midterm elections Tuesday, according to Gallup's final poll. The result of that question has lined up with the actual election outcome every time Gallup has asked it since 1946.

Fifty percent of Americans believe Republicans will stay in power in the House, while 44 percent believe Democrats will take control.

In a larger note of confidence, Americans also believe that Republicans will retain the majority in the Senate. Sixty-one percent say Republicans will hold power in the Senate following the elections, and 33 percent believe that Democrats will take control.

The poll concluded that Democrats are much more worried than Republicans about the outcome of the 2018 midterm elections.

Eighty-one percent of Democrats say they are very or somewhat worried about the fallout of a Republican controlled Congress, in either one or both chambers. On the other hand, 66 percent of Republicans say the same about a Democrat win in one or both houses.

The survey was conducted from mid to late October.
