Does John McCain’s temper concern you?
Temperament
Journalist Adam Clymer notes of McCain that, “There is no question that he sometimes loses potential allies by his penchant for telling off other senators.”[31] Todd Purdum remarks upon a “temperament that routinely put[s] him atop insiders’ lists of the most difficult senators on Capitol Hill.”[11] A 2006 Washingtonian survey of Capitol Hill staff ranked McCain as having the second “Hottest Temper” in the Senate.[32] Former Senator Rick Santorum says that, “John was very rough in the sandbox. Everybody has a McCain story. If you work in the Senate for a while, you have a McCain story. … He hasn’t built up a lot of goodwill.”[33] Writer Elizabeth Drew quoted a senator who admired McCain as saying, “Dealing with John McCain is kind of like dancing with a cactus.”[34]
In 1989, McCain screamed at Senator Richard Shelby an inch from his face, during a heated cabinet nomination battle for McCain’s friend John Tower.[35][36] In 1992, McCain and Senator Chuck Grassley got into a heated argument, with shoving and profanities, over a POW/MIA committee issue and did not speak to each other for two years, before reconciling.[35][36] At a meeting in 2007 on immigration legislation, fellow Republican Senator John Cornyn objected to McCain: “Wait a second here. I’ve been sitting in here for all of these negotiations and you just parachute in here on the last day. You’re out of line,” to which McCain replied, “Fuck you! I know more about this than anyone else in the room.”[37][38]

…I believe there is a BIG difference between having strength as a person and having a bad temper, Part of being a strong leader is being able to control your emotions and deal with situations properly.
