An overwhelming majority of Americans say it’s important for politicians to treat each other with civility, according to a new Hill-HarrisX survey released Monday. Ninety percent of respondents nationwide said that it’s important for politicians to be civil to one another, compared to just 10 percent who said they didn’t think it was important. Voters across the political spectrum said civility was important to them. An equal share of Democrats and independents — 90 percent — were in agreement, as were 89 percent of Republicans…The Hill-HarrisX survey was conducted online among 1,001 registered voters from Jan. 30-31. The margin or error is plus or minus 3.1 percentage points.
