The headline is a bit of a clickbait.

The text says:

1) Some pro-Trump people are people of Ukr ancestry but who have or whose families have been in the USA a long time- so their kneejerk Republicanism is like what Cubans or some Vietnamese Americans feel. Some old-fashioned people see  Trump as a 'strongman' they approve of.

2) Some people feel the Dems are not going far enough- an analogy would be not preferring the Dems over Trump on Gaza because they prefer purity to the lesser of two evils.

So it's nothing like the idea that people take a measured view and then plump for Trump.
