One interesting point in the article you posted rather than OP's is that according to Ipsos only 17% of Americans approve of taking Greenland. I have no clue what the truth is but that number 'feels' a little more accurate.
In short that would mean 17% of Americans are ride or die MAGA which sadly is a believable number.
Honestly I actually think this is a good sign. There was a point toward the end of 2024 when Trump could have come out and said the moon is made of cheese and polls would say 50% of Americans agree with him. The fact that in less than two years Trump has lost 50% of his base is insane. He's is hemorrhaging support.
If numbers keep moving this way the midterm elections, which happen later this year will be interesting to say the least.
