How hard are the suburbs really trending D?

[redeagleofficial]

I will admit that white collar suburbs are trending D hard (Suburban Denver and DMV for example), but blue collar suburbs (Macomb County, MI for example as well as counties in Ohio and other places) are trending R.  Trump actually won the suburbs by 4, after Romney won them by just 2, according to the 2012 vs 2016 exit polls.  If Trump has solidified his support from the establishment/neocon/Ben Shapiro style voter, could he actually improve/not lose too much ground in the suburbs from 2016? (assuming the economy is good)

I think you might be underestimating how hard the suburbs have swung against the GOP over the past four years.  Yes, places like Macomb County were nice pickups for Trump in '16, but if the midterms were any indication (and they may or may not be), Trump has to do more than just riding a good economy to gain support in the suburbs. 

[Existing in the context]

Enough that the last 2 Republican house leaders (Excluding Boehner and Ryan) home districts are represented by two liberal black women.

It is true there are a wide variety of suburbs here but when people mention suburbs politically it usually means the well educated suburbs or rich. There are a large mix overall.
