Steve Karnacki on Chris Hayes’ All In gives the following stats in points over one party or the other:
W 51 B 8 H 28 pts for GOP W 39 B 84 H 63 pts for Dems
Gender Men 48 Women 37 for GOP Men 44 Women 56 for Dems
Education 1995 college ed GOP+15 2018 Dems +15 (complete switch)
Age by generation groups:
Silent 70s/80s +9
Boomers 1946-64 +2
Gen X +5
Millennials +27 (the only group where
Whites support Dems more than the GOP)
Millennial men +8
Millennial women +47
So for example, millennial women give Dems a 47 pt. lead over the GOP.
The boomers give Dems a 2 pt lead and Blacks give Dems an 84 pt lead.
I have no idea why I can’t type little tables like this but I hope it comes out OK.
