Opinion: What's with the silence from former Trump heavyweights?

Contributing sentiments towards policy:

65% : "The letter, the ad, Harris' trolling -- all of that is well and good, but we need to hear unambiguously from those White House, Cabinet and military notables who actually saw and conversed with Trump regularly.
54% : But when asked if Trump is fit to hold the office again, he demurred: "That's the judgment that the American people have to make."
48% : McMaster said he didn't agree, though he did volunteer that Trump "sees in authoritarian leaders," especially Putin, "the qualities that he wants other people to see in him."
43% : We know what they think about Trump.
42% : On Monday, 10 retired military officers, including six former generals and two admirals, released a letter in which they not only condemned Trump but also endorsed Harris as "the best -- and only -- presidential candidate in this race who is fit to serve as our commander-in-chief."
36% : Last month, promoting his latest book, "At War with Ourselves: My Tour of Duty in the Trump White House," McMaster told CBS News that Trump was "nasty," refused to prep, made contrarian decisions "just to spite" his advisors, was "addicted to adulation" and fomented "an environment of competitive sycophancy."
34% : Yet they served in civilian roles and saw Trump as most Americans could not.
25% : Another possible reason for their reticence: It's well-documented that taking on Trump causes him to attack, which in turn provokes threats of violence from his most rabid supporters.
23% : What could better tip the few undecided voters against Trump than former military leaders, on national TV, giving witness to his disregard for the Constitution, the rule of law and America's national interests?
22% : Trump, they wrote, "is a danger to our national security and our democracy.
17% : Still more, including former director of national intelligence and former Sen. Dan Coats, who privately fretted that Trump was somehow beholden to Russian President Vladimir Putin, have been altogether silent.
12% : He said Mattis and Secretary of State Rex Tillerson considered Trump a danger to U.S. interests.
