One year from now, November 2020, in the aftermath of the 2020 election, regardless of whether Trump is reelected or not, we'll already start to have a couple of super early 2024 primary polls. What will those polls look like on the GOP side? Who will be in 1st, 2nd, 3rd, etc.?
Since I doubt prospective candidates like Ron DeSantis or Josh Hawley will be well known beyond their home states by then, I'm assuming that the polls will be dominated by already well known names. I'd assume that Pence will be in 1st place, but some retreads from 2016 like Cruz and Rubio are also well known enough that they'll probably be included in the poll and getting at least somewhere in the mid- to high-single digits. Other names that might show up in the polling might be Lindsey Graham, Rand Paul, Nikki Haley, Paul Ryan, or even Mike Pompeo:

Also, flashback: Here's an early 2020 primary poll taken as of October 2016:
