Back in 2016, in the Republican debates, I thought Rand Paul came across as a Senator, in the best sense of that office, rather than as an executive.
A great Senator cannot make policy by himself and also by nature of political realities must on occasion vote with a flawed majority. However Rand Paul is a great Senator in the tradition of Cato the Elder. Despite the ignorance and even malfeance of those around him he speaks truth to power on behalf of the American people. History has shown that these isolated great men are eventually heard and things do change.
