Got put on to an excellent site that is tracking approval/disapproval of Trump by state, on a monthly basis. We were talking about this recently, regarding the GOP's electoral chances in November, and Trump's shot at re election in 2020.
So which states did Trump win that he's even or underwater in now?
State (Jan 17 Approval-Disapproval/July 18 Approval-Disapproval)
Arizona (55-35/48-48)
Iowa (49-40/46-50)
Michigan (48-40/44-52)
Ohio (51-37/47-49)
Penn (49-39/46-51)
Utah (58-31/48-48)
Wisconsin (47-41/41-55)
That's gotta be somewhere in the range of 60-70 electoral votes that look likely to shift at present. The other danger Trump is facing, is the amount of GOP won states with high disapproval numbers:
State (Jan 17 Disapproval/July 18 Disapproval)
Florida (34/45)
Georgia (35/45)
Indiana (33/45)
Kansas (32/45)
Missouri (34/45)
Montana (32/44)
N Carolina (35/47)
Nebraska (33/46)
N Dakota (33/46)
Oklahoma (27/40)
S Carolina (31/41)
Tennessee (28/40)
Texas (34/43)
Now, I don't really expect Republicans lose (m)any of those states in 2020, but where that does get important is in the distribution of assets. If any of these turn into legit battlegrounds, that's less money, personnel, etc that can be spent on legit swing states where the results are very much in doubt. Every dollar spent defending traditional home turf is a dollar that can't go for TV adds in Ohio, or Pennsylvania.
When you look at his approval numbers, they haven't wavered much in a lot of the important spots since the election. But they were pretty much historically low from the onset, and the disapproval numbers have sky rocketed pretty much across the board.
