For better or worse, Trump does not get too influenced by individuals other than himself, but if anybody has influenced him lately it has been Lindsay (as much or even more than Rubio, with Vance not counting for too much). For example, Lindsay has been a staunch supporter of both Ukraine and Israel and, of course, the US military, heavily based in his own state. Recently he has been a successful counter-weight to Trump being wishy washy on Ukraine.
