Everything about this is dumb—naming a road after a President who didn't really materially affect the region the road is in one way or the other, going to the extent of amending law on who is eligible for such an honor to allow it to happen, and then the desperate scramble to find the money for it (I think the $1,000 quoted in the article is overestimating it, honestly; the only way you'd get it that high is if you included the wages of every single employee who touches that sign and the gas to drive it out to Cimarron County from wherever it's printed).

No reason to unless the thread gets contentious—this sort of political wrangling over roads is 100% on topic.
I don't believe the naming rule exists. I lived in St Louis when a portion of it was named the Mark McGwire Highway who is still very much alive. Rather humorously, the name was later removed after McGwire's involvement in baseball's steroids scandal. I believe the Bushes each have a highway named after them in Texas and both were named while Bush Sr was alive.
This naming rule appears to be a matter of Oklahoma law, which obviously wouldn't apply in Texas or Missouri.
I wish Oklahoma law completely banned these sorts of memorial designations no matter who they were for. Our roads are littered with hundreds of signs naming every random stretch of two-lane road and every culvert after state troopers, state legislators, and individual soldiers. None of these names recognize anyone who is well-known outside the immediate area (and sometimes not even then; the stretch of Interstate outside my childhood home is named after someone I've never heard of). Rarely are these names used to identify the highway. It does nothing but waste money and clutter the roadside with unnecessary signs.
I know that realistically the Legislature will never stop pandering to random people by declaring more and more memorial designations, so it would be pretty funny if ODOT just started printing them on milemarker blanks with 2" lettering. Technically, that would comply with the law!
