Some voters said the race has taken a toll on their personal relationships. Seven percent reported having lost or ended a friendship over the campaign, Monmouth found.

The poll found broad dissatisfaction not only with the presidential race, but also with the tenor of political discourse.

Only 30 percent of voters said the harsh language used in politics today is justified, according to the poll. Another 65 percent of voters said the language is unjustified.

Among voters who support Trump, the Republican presidential nominee, 47 percent said the campaign's harsh language is justified. But among those who support Clinton, the Democratic nominee, only 17 percent agreed.

Half of voters said the harsh language tends to come equally from supporters of both Trump and Clinton. Another 37 percent of voters said the harsh language tends to come more from Trump supporters, and 11 percent said it comes more from Clinton supporters.

Twenty percent of voters said they are "angry" with Washington, while 66 percent said they are "dissatisfied."

Only 9 percent of voters said they are "satisfied" with Washington and just 3 percent reported being "happy."

The poll was conducted from Sept. 22 to 25 among 802 registered voters. The margin of error is 3.5 percentage points.
