Democrats need a net gain of two seats to retake the Senate. Republicans are currently predicted to hold their majority. FiveThirtyEight gives them a 5 in 6 chance of maintaining their majority.

However, the same prediction expects Democrats to flip the House. FiveThirtyEight gives them a 6 in 7 shot at doing so.

Sunday's poll also showed a widening divide between Democrats and Republicans in the midst of a heated political climate.

Among Republican voters polled, 70 percent said that the Democratic Party is composed of people with different values and only 30 percent said the left was advocating for policies with which they disagreed.

Likewise, 66 percent of Democrats told pollsters that the GOP stood for different values than they did, while 34 percent said it advocated for policies with which they disagreed.

In Arizona, pollsters spoke to 972 likely voters from Oct. 23-26 and the results have a margin of error of 4.1 points.

In Indiana, pollsters spoke to 975 likely voters from Oct. 23-26 and the survey has a margin of error of 3.7 points.

The Florida poll has a margin of error of 4 points. Pollsters interviewed 991 likely voters from Oct. 23-26.
