It's amazing how s**t scared they are of Trump.
You are right. There are two times when a clandestine enemy will betray his disguise:
1. When he thinks his side is close to winning and it's safe to be in the open; or
2. When defeat is inevitable and there is nothing left to lose.
The former is a proud and jubilant celebration, while the latter is a desperate flailing for a lucky punch. These people aren't happy and they aren't winning. They are afraid.
