Dems have to double down on both but the key to winning the EC is to flip WI, MI, PA where Trump won by less than 1%, they are easily winnable with the right candidate. The Sun belt will come into play in 10-12 years with a more diverse population & young people coming into the voting bloc.
Dems so far 1 Sen fron OH, 2 from MI, 2 from MN, 1 from WI, 1 from PA, that's 7, you can't make that number easily. The Senate & the WH will be lost for a generation, for atleast 10-12 years.
In the short term, you appeal to the rust belt, pretty indisputable IMO ! Rust Belt voters in Healthcare, Education, Trade (Anti-Free Trade is a classic left wing issue), Infra, Minimum Wage, etc mesh more with the Dem's than with the GOP!
Thing is, it's not hard to see a 2020 scenario where all of those states keep trending and vote for Trump by 5% anyway, like Florida for Bush in 2004. It's not at all obvious that MI/WI/PA will be closer than FL/GA/NC next time. It would be really, really bad to spend $50M in Michigan and $500K in Georgia and lose both by 3%. Democrats have sucked at winning close elections for the past 50 years. Perhaps it's because they spread themselves too thin trying to be everything to everyone?
