the mid-term election.

Suburban women went for Hillary. Suburban white men went for Trump (there was a breaddown between college education and non-college educated, but oveall Trump still won.

In 2018, the suburbs went blue. This is why you saw so many districts flip. The districts that flipped were to the greatest extent districts that touched places like Phoenix, Dallas, Charlotte, and so forth.

It should be noted that when we redistricted in 2010, the districts were drawn (nice word meaning gerrymandered) by Republicans, who put an awful lo of thought and work into the process. The districts were drawn in such a way to permit safe Republican control of Congress even during 50-50 national voting splits. How? By carving out districts radiating from cities so they could win 3 districts by 53-47 while losing one districts by 25-75. It was pretty genius in an evil way.

However, the strategy depended upon a political constant---that white suburban voters would be reliable Republican voters. The scheme worked perfectly as intended until Trump happened to the Republican Party. Suddenly educated suburban voters abandoned the Republican Party and its lack of values other than political power. And, yes, there's been a myriad of polling to suggest that college educated suburban voters, male and female, will be voting, if not for Biden, at least against Trump in 2020.
