Donald Trump is his own is favorite, and possibly only, advisor, and Democrats would do well to respect that and take some sound advice from Napoleon Bonaparte.

Trump's negative ratings have been rising steadily along with the number of Republicans elites who have disavowed his rantings – Speaker Paul Ryan, Senate Majority Leader Mitch McConnell – or have said they will not vote for him – Maryland Gov. Larry Hogan is the latest on a list that includes the entire Bush family, Mitt Romney, Columnists David Brooks, George Will and Charles Krauthammer, Bill Kristol, Joe Scarborough, former deputy secretary of state Richard Armitage, Sen. Ben Sasse, Rep. Fred Upton.

Ryan hasn't un-endorsed Trump – at least not yet – but he had some very unusual advice for his fellow Republicans:  vote your conscience.  Translation, I may have to vote for him, but you don't.

Sen. Bernie Sanders (I-Vermont) hasn't endorsed Hillary Clinton because he is still focused on two of his highest priority irrelevant battles – firing the chairwoman of the Democratic National Committee and ending Super Delegates – that have nothing to do with winning the presidential election or advancing the substantive issues he campaigned on.  

Clinton has already begun spending millions on her advertising campaign in battleground states.  She might want to pause and consider Napoleon's advice:  "Never interrupt your enemy when he is in the process of destroying himself."

There is some dispute about his exact words, but the message is clear and one the Democrats would do well to heed.
