Have people stopped listening to celebrities? Judging by the midterms, it appears so. From Jon Hall at fmshooter.com:

Ahead of the 2018 Midterm elections, many Hollywood celebrities threw their hat in the ring to back a particular candidate in hopes of boosting their chances of winning their respective races.
For instance, Taylor Swift made headlines last month when she endorsed Democratic Senator Phil Bredesen in Tennessee’s elections…

Bredesen, however – even with Swift’s endorsement – lost handily to Republican Marsha Blackburn on election night.
