It would have been perfectly reasonable to say something like, "As long as the elections are free and fair, of course I'll accept them". That would have given him plenty of room to fall back to the next version of the GOP's "Big Lie". But instead we get this:
Kristen Welker: “Will you commit to accepting the election results of 2024?
Tim Scott: “At the end of the day, the 47th president of the will be Donald Trump”
Welker's question is like asking a football team/defense attorney what they'll do if they lose. When engaged in a competition of wits, you don't acknowledge the possibility of losing until it's already been handed to you. Anything else smacks of defeatism, which is not a very good trait to have as a presidential candidate. Campaigns in the past have given similar non-answers to these types of questions.
By being so on the nose about it, Scott is also appealing to Trump's braggadocio. He's trying to keep himself ahead in the veepstakes.
Has it ever occurred to you that maybe politics shouldn’t be treated like a sports match?
