(I'm going to start adding some commentary, where appropriate)
** 2018 Senate:
-- WV: 1892 Polling has Dem incumbent Manchin tied 45-45 with GOPer Morrisey [MOE: +/- 4.4%]. Poll was commissioned by the Morrisey campaign. => This seems pretty clearly an effort to counter perceptions that this race is already over - the DSCC pulled ads yesterday. Public polling has had Manchin with leads of about ten points.
-- CA: PPIC poll has incumbent Feinstein up 40-29 on de León [MOE: +/- 4.4%].
-- MI: EPIC-MRA poll has Dem incumbent Stabenow up 56-33 on GOPer James. [MOE: +/- 4.0%].
-- PA: F&M poll has Dem incumbent Casey up 50-33 on GOPer Barletta [MOE: +/- 6.1%].
-- IN: Former Senator Lugar refuses to endorse either candidate.
** 2018 House:
-- CA-50: Monmouth poll has GOP incumbent Hunter up 49-41 on Dem Campa-Najjar in their potential voters model. In midterm model, Hunter up 3-38; Dem surge model, Hunter up 51-40 [MOE: +/- 4.9%]. [Trump 55-40 | Cook: Lean R] => Hunter is currently under indictment for campaign finance violations, which is why the Dem is about 20 points closer than he was previously. But it's just a really red area. The DCCC is cancelling their San Diego ad buys, probably meaning they a) see CA-50 as out of reach, and b) see CA-49 as in the bag.
-- AZ-04: OH Predictive poll has GOP incumbent Gosar up 57-25 on Dem Brill [MOE: +/- 5.1%] [Trump 68-28 | Cook: Solid D] => This is the one where all of Gosar's siblings made an ad endorsing Brill. It was a great ad, but a 40 point Trump margin district.
-- Democrats still expanding the map, as numerous unheralded races are believed to be within 10 points.
-- Cohn: Undecided voters may help Dems more in Sunbelt than Midwest.
** Odds & ends:
-- CA gov: Same PPIC poll has Dem Newsom up 51-39 on GOPer Cox. | Downballot, Proprosition 6 (gas tax repeal) fails 39-52; Proposition 10 (allowing municipalities greater power to enact rent control) fails 36-48. [Cook: Solid D]
-- MI gov: Same EPIC-MRA poll has Dem Whitmer up 45-37 on GOPer Schuette [Cook: Lean D] | Downballot: SOS: Dem Benson up 40-31 on GOPer Treder Lang. AG: Dem Nessel up 38-32 on GOPer Leonard.
-- PA gov: Same F&M poll has Dem incumbent Wolf up 52-30 on GOPer Wagner. [Cook: Likely D]
-- SD gov: ALG poll has Dem Sutton up 45-42 on GOPer Noem [MOE: +/- 4.4%]. Poll was commissioned by the Sutton campaign. [Cook: Likely R] => This one has been a sleeper favorite for a while. Sutton is very well known and popular in SD - he's a former professional rodeo guy who suffered a tragic accident - and presumably the soybean tariff is none too popular. Still something of a long shot, but not a foregone conclusion.
-- FL gov: GOPer DeSantis hires new campaign manager, as polls show Dem Gillum with consistent leads. [Cook: Tossup]
