This tells me he's unable to make quick judgments or quickly determine/ascertain if a person is credible and or legitimate. In addition, I personally find people who flip like that regarding their political persuasion or beliefs, quite suspect. We'll see what happens.

Based on these criteria of quickly evaluating someone, many of the people on Free Republic were not enthusiastic Trump supporters in 2015-16. There were quite a few Freepers who supported others during that primary election cycle in 2015-16. Yet today, almost everyone here supports Trump. His actions as president impressed many who had not supported him in the primaries.
