Some of the issues in the OP like LGBT were not relevant in 1988, and some of those that were like abortion did not drive the electorate the way they do today. Global warming was a decade away from the national debate and Appalachian coal country was still with the Dems.
Why didn't abortion drive the electorate the way it does today? Roe v. Wade had already been around for some time.
Wasn't quite as politicized. First, the Summer of Mercy hadn't happened and groups like Operation Rescue were still fledgling. Additionally, there were many pro-choice GOPers and pro-life Dems, so abortion wasn't a partisan thing.
