If one were to draw a Venn diagram between ardent Trump supporters and ardent Trump critics, within the intersection of the two, you’d likely find individuals like the junior Republican senator from Nebraska, Ben Sasse.
Prior to the 2016 election, many people staked out their allegiances. The hard-core Trump and anti-Trump people had already decided to go all-in to support him or to support his impeachment. The loudest groups now are those who were Trump skeptics but chose to vote for him as opposed to Hillary, and those who didn’t vote for him but didn’t jump to the other side. It’s those latter two groups that became the loudest critics of Sasse and others like him, but for different reasons.
Despite the differing reasons, it certainly hasn’t alleviated the annoyance of their grumblings. Sasse, by almost any measure, is one of the most conservative members of the Senate. Elected in 2014, he was voting for conservative-backed legislation when Trump was making his way down the escalator in Trump Tower to announce his candidacy for president.
