Probably because neither of them ever learned to ride a bike, and certainly never rode all over town on a summer day when they were kids. Emotional bankrupts, both of them, nary a speck of joy in their souls.
I remember the Cons going after bike lanes back in the Obama years because there was a mention of their benefit by the [gasp!] United Nations. These morons went absolutely bat-crap insane over it.
Want to 86 our lanes? Fine, we'll just ride in yours (lots of "Bikes May Use Full Lane" signs here).
