Where I live, it's much more conservative than other places because of religiosity, but I would say that the bigger issue nationally for the GOP is that they are not culturally conservative, not that they are not socially conservative. That's especially evident in that many suburbs had no problem with social conservatism from the GOP for decades, but flipped en masse when the GOP started to focus on cultural conservatism.
What do you mean by culturally vs. socially conservative? Attitudes on e.g. gay rights have shifted seismically in the college+ demographic over the past 15 years and college+ as a whole appears to lean pro-choice vs. non-college. Some of this is Millennials growing up and moving to the suburbs, but it also looks like a lot of people really changed their minds.
The one major issue on which college+ suburbs still strike me as socially conservative is monogamy/waiting until marriage to have kids, and Democrats are probably better positioned to appeal to suburban voters on those issues post-Trump and MeToo.
Nearly everyone over 35 who supports gay marriage has changed their mind on the issue at some point, so there's that to consider.
