Is it less than 50%? The AP still shows Trump getting 50% of the vote. Maybe if you take it out to the fifth decimal place or something it's a tick below, who knows. Regardless, given that 0.5% of the vote went to RFKjr, I think we can safely say the majority is supportive of this administration.
And really, while some believe they aren't "contributing to the problem" by voting for a non Trump/Harris candidate, really what they're doing is implicitly giving their support for whichever of those two win by not making any attempt to vote for a viable candidate against them.
