About two months ago Republican Sen. John McCain of Arizona likened Cruz and Paul, and others to "wacko birds" for their style of confrontational politics. Paul responded to the party's 2008 presidential candidate and 5th term senator by saying, "The GOP of old has grown stale and moss-covered. I don't think we need to name any names, do we?"
