[PJ]

Alabama: Doug Jones

Arizona: Sinema, because I want to win this seat, but I'd be open to a more progressive challenger.
California: De Leon, or any progressive challenger to Feinstein that isn't a silicon valley puppet.
Connecticut: Probably Murphy, but I'd be open to a left wing challenger. I don't know enough about this Adams woman.
Delaware: Carper, but see above.
Florida: Nelson
Hawaii: Hirono
Indiana: Donnelly
Maine: King, even though he's not perfect, I don't know what to make of the democratic candidate.
Maryland: Some progressive challenger to Cardin.
Massachusetts: Warren
Michigan: Stabenow
Minnesota: Klobuchar
Mississippi: whatever democrat
Missouri: May support primary challenger Earl*
Montana: Tester
Nebraska: just run a berniecrat
Nevada: Rosen, unless someone better runs
New Jersey: Wisniewski, or just a non-Menendez Democrat
New Mexico: Heinrich
New York: Gillibrand is fine
North Dakota: considering Peyer primary challenge*
Ohio: Brown
Pennsylvania: Probably Casey
Rhode Island: Whitehouse
Tennessee: Bailey
Texas: O'Rourke
Utah: Wilson, but would possibly vote for an Independent conservative like McMullin if there's a chance of unseating Hatch and screwing with McConnell
Vermont: Sanders
Virginia: I actually am coming around to Kaine as one of the better establishment candidates
Washington: Cantwell, maybe a progressive challenger
West Virginia: Swearingen*
Wisconsin: Baldwin
Wyoming: run a berniecrat

*a little ambivalent about these, but I want to push all democrats toward supporting medicare for all etc.

[Former President tack50]

I'd endorse the Democratic candidate in all races except in these cases:

Maine: Angus King (I)
New Jersey: Abstain. Vote third party if a sane one gets in the ballot. If Menendez gets primaried out then vote for whoever the democratic nominee is.
Vermont: Bernie Sanders (I)

I don't know enough about the primaries to endorse candidates there.

[America's Sweetheart ❤/𝕿𝖍𝖊 𝕭𝖔𝖔𝖙𝖞 𝖂𝖆𝖗𝖗𝖎𝖔𝖗]

Just a few I'll endorse here:

Susan Collins (R-ME)
Mitt Romney (R-UT)
Lisa Murkowski (R-AK)
Joe Manchin (D-WV)
Tim Kaine (D-VA)
Jim Hood (D-MS)
Austin Peterson (L-MO)
Angus King (I-ME)

Just a few I'll endorse here:

Lisa Murkowski (R-AK)
Joe Manchin (D-WV)
Tim Kaine (D-VA)
Jim Hood (D-MS)
Austin Peterson (L-MO)
Angus King (I-ME)

Collins and Murkowski aren't up for reelection until 2020 and 2022 respectively.

I have now endorsed a declared candidate in every race, except for VT where the Republican field remains unclear. Of course, the endorsement will have to change if my preferred candidate loses the primary, assaults someone, etc.

In total, I have endorsed 24 Democrats (69%), 10 Republicans (29%), and 1 Independent (3%) for these elections.
