That’s generally the consensus, that young men are roughly as conservative as they were historically, but women are more left-wing (although maybe a bit less than expected, given recent election results).
Results from Reagan’s 1980 election win look fairly similar: https://ropercenter.cornell.edu/how-groups-voted-1980, excepting that women and men were voting in similar ways for each age group, and bigger margins to Reagan in the older groups.
EDIT: Nevermind this doesn’t actually show age by gender data.
Most newer Garmin devices should work since 0.82 (and earlier with nightly). It’s not feature complete compared to using Gadget Connect but should be enough for most use cases, unless you really care about the social/awards aspect and some of the deeper metrics (although if you’re handy with SQL you can handle that yourself).
Not being able to set an event date and have “daily suggested workouts” follow that is my only annoyance, although I’ve been happy just using the defaults for now.
