With that exact question as written on Politics SE, I'd first be closing as "not notable". You'd need a notable claim. I suspect you aren't asking off the top of your head, so maybe you can easily find a notable claim.
I'd next close as a current event. As you point out in the question, it's still some time before Trump's term expires. On the other hand, maybe that's not fair because if he's already the most pardoning POTUS, then the answer won't change because of his own actions. My rebut would be that it's only a month until he can no longer take the action at all, so it can wait until then, when deep and comprehensive analyses of his presidency is likely to exist and we know the exact numbers of the answer won't change in the near future.
Then there's a possible "user interest" issue, as recently suspected to exist by one of our longtime high contributors. Maybe it's technically on topic and wouldn't be closed, but it might get net downvotes. I personally would be inclined to downvote. I do not find the question interesting and believe the answer trivial, whether 'yes' or 'no'. But I wouldn't close it, since there's no "conflicts with fredsbend's interests" close rule for this site, as much as I might like it ;)
I can't speak for things on Politics SE, but I do interact with some of their regulars a good deal, so if their criticism of the question is how to measure "close to the President", I'm inclined to believe it's honest criticism, not cover up for "Republican wrongdoing". I think you'll get exactly the same criticism here too. We're even more obsessed with measurable and empirical answers. I don't think "Obvious, I know it when I see it" definition will satisfy our regulars.
Now, I don't want to discourage you from asking politics questions on Skeptics SE. Indeed, I like politics as a topic. Unfortunately, I think as a topic on this site it's been too often used as a megaphone for low gravity, politically embarrassing nonsense. I understand "low gravity" is a bit of a subjective judgement, but I'd just point you to about half of our Trump questions over the last five years (it's a lot) and challenge you to prove they aren't much better than "trivial partisan crap slinging". Maybe you think that's cynical. Maybe you haven't read those questions yet. For me, politics questions need some meat in them. If you can reasonably say the answer doesn't really matter a year from now, you probably shouldn't ask it.
