Barlow only supported Cheney before Cheney became known for supporting Bush's war. And then, Barlow stopped supporting Cheney, which, in my opinion is a honoroable move because Barlow didn't want to support what Cheney supported because it was against Barlow's ideals. I'm honoring Barlow's decision.
In addition, Barlow has been a vocal critic of Trump before Barlow unfortunately died in 2018.

Politics is not easy because many peope come and go. People should always review their own positions, which Barlow did. No many people are reconsidering their own position because often it's easier to stay in power by not changing anything, by making convenient decision.
But Barlow stood up for what is right.
