I have no doubts about the infiltration by Communists. It's actually ironic that the same people (largely Democrats and the left) who routinely scoff at any concerns about Communist attempts to subvert our government, are now screaming about the Russians hacking our elections. These are the people who to this day label McCarthy an evil man, and who label attempts to protect ourselves against Communist subversion McCarthyism.
Regarding Strzok’s wife, you may be right. She did land that job at the SEC in 2016, and I'm sure that was totally independent of any connections and influence..
