FiveThirtyEight is collecting general election polls for 2018 U.S. Senate, U.S. House and gubernatorial races, as well as presidential job approval and generic ballot polls (which ask which party people would vote for in a congressional election). Polls are listed by the date that FiveThirtyEight collected them, although House, Senate and gubernatorial polls that were released before June 28, 2018, are listed under the last day that the poll was in the field. Polls from firms that are banned by FiveThirtyEight are not shown. Pollsters that did not release any horse-race polls within three weeks of an election since 1998 do not have a grade and are treated as a C+ by the grade filter.
* Polls marked with an asterisk are internal polls, conducted or sponsored by a political party or by the campaign of one of the candidates.
