Yep. Gen X has consistently been the most pro-GOP generation over the past 8 years. It makes sense. The first Gen X'ers came of age as Carter's presidency was falling apart, most of them came of age under the Reagan Revolution. That was followed up by the 90's, a pretty conservative decade politically despite having a Democrat in the White House for most of the decade.
The Democratic platform has moved to the left since then, no doubt about it. Of course, while Democrats have moved the the left, Republicans have gone even further right; so far they've fallen off the rails and into fascism entirely. But Gen X didn't come up with fascism as the boogeyman, it was communism and socialism.
I don't think Gen X has gotten more conservative. I think they have always been conservative and the low effort "SoCiAlIsM!1!1" cries from the GOP that we clown on Boomers and Silents for falling for also probably work on Gen X because the environment in which they came of age.
