The Trump coalition is broad and complicated, but I believe many Trump fans are well-meaning. I have spoken at length with many of you, both inside and outside Nebraska. You are rightly worried about our national direction. You ache about a crony-capitalist leadership class that is not urgent about tackling our crises. You are right to be angry.

I’m as frustrated and saddened as you are about what’s happening to our country. But I cannot support Donald Trump.

Please understand: I’m not an establishment Republican, and I will never support Hillary Clinton. I’m a movement conservative who was elected over the objections of the GOP establishment. My current answer for who I would support in a hypothetical matchup between Mr. Trump and Mrs. Clinton is: Neither of them. I sincerely hope we select one of the other GOP candidates, but if Donald Trump ends up as the GOP nominee, conservatives will need to find a third option.

Mr. Trump’s relentless focus is on dividing Americans, and on tearing down rather than building back up this glorious nation. Much like President Obama, he displays essentially no understanding of the fact that, in the American system, we have a constitutional system of checks and balances, with three separate but co-equal branches of government. And the task of public officials is to be public “servants.” The law is king, and the people are boss. But have you noticed how Mr. Trump uses the word “Reign” – like he thinks he’s running for King? It’s creepy, actually. Nebraskans are not looking for a king. We yearn instead for the recovery of a Constitutional Republic.
