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 conducted after June 28, 2018, are listed by the date that FiveThirtyEight collected them; polls conducted before then are listed under the last date 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 partisan polls. Partisanship is determined by who sponsors the poll, rather than who conducts it. Polls are considered partisan if they’re conducted on behalf of a candidate, party, campaign committee, or PAC, super PAC, 501(c)(4), 501(c)(5) or 501(c)(6) organization that conducts a large majority of its political activity on behalf of one political party.
