Enthusiasm doesn’t lead to anything most of the time. Throughout history the greatest Presidents all had to make difficult decisions that either went against their ideals or were questionable if they had the right to do them. Anyone can run on grand ideas, but once you’re in the seat the unattended consequences are revealed to you, and unless your a monster who doesn’t care, they have to be dealt with.

An example that made me change my mind about some things under the Obama administration was watching documentary series on declassified CIA/FBI counterterrorism incidents. The number of plots they were stopping was overwhelming. And if those interviewed are to be believed those were only a small fraction of the situations they dealt with.
