I would have suggested Trump have legislation passed that adds "political calls" to the group of callers that have to obey the Do Not Call laws, so that "political groups" cannot call numbers on the federal Do Not Call list.
Every morning for the past month or so, caller id "Tea Party" calls at 9:15 AM. They are using 4 or 5 different numbers and call back often, but always at 9:15 AM to start the day.
