How do you buy Sen. John McCain’s (R-Ariz.) vote on the health-care bill? Or consider the recent scrap between Sen. Lisa Murkowski (R-Alaska) and Interior Secretary Ryan Zinke, who called her to complain about her no vote on debating the repeal of Obamacare. Trump had already tweeted his disappointment. Zinke and Trump didn’t understand how power works here.
