Who Hasn't Donald Trump Insulted?

The latest institution to be denigrated by the White House is the Congressional Budget Office. Sean Spicer, the President's ditzy Press Secretary, said that the CBO's financial analysis of the Republican's proposed 'American Health Care Act,' should not be trusted. This preemptive strike against the CBO is due to widespread reports that the analysis will show the AHCA to be vastly inferior to the Affordable Care Act, covering far few people at far higher premiums.
Trump has now dismissed, denigrated, or demeaned the Intelligence Community, the military officer corps -- "rubble" -- Senator John McCain, because he was captured during the Vietnam War, the U.S. Judiciary, former president, Barack Obama, the U.S. Electoral System, and the Media, Muslims, Mexicans, to say nothing of past Republican presidential nominees, and of course, "Crooked Hillary," and women generally, for whom he demonstrates appalling disrespect.
The only entity for whom the American President, Donald J. Trump, exhibits respect, and indeed admiration, is Russian President, Vladimir Putin. I wonder why that is.
