Republicans used to care a lot about how a president comports himself, and whether he acts at all times with the dignity his station demands.

“Is President Obama Disrespecting the Oval Office?” Fox News asked in 2010, with a link to images of Mr. Obama and his aides tossing a football, or eating apples just inches from the Resolute desk.

“Wear a suit coat and tie,” said Andrew Card Jr. , President George W. Bush’s former chief of staff, in reaction to pictures of Mr. Obama in shirtsleeves in 2009.

“I do expect him to send the message that people who are going to be in the Oval Office should treat the office with the respect that it has earned over history,” Mr. Card said.

But hey, that was then! In 2017, there’s a whole new bar for tolerable conduct by the commander in chief. Our original guide cataloged several dozen examples. Almost five months later, it’s clear that an update is necessary. This expanded list is meant to ensure that Paul Ryan, Mitch McConnell and other congressional Republicans never forget what they now condone in a president.
