It's OK - lots of others have changed their minds about Trump, so I guess BK can too:
Rick Perry (former Texas Governor)
“Donald Trump’s candidacy is a cancer on conservatism, and it must be clearly diagnosed, excised and discarded.” July 22nd 2015
“I'm going to support him and help him and do what I can. He is one of the most talented people who has ever run for president I have ever seen.” May 5th 2016, CNN
Lindsey Graham (Senator from South Carolina)
“He’s a race-baiting, xenophobic, religious bigot.” December 8th 2015, CNN
“We talked about national security, and told some jokes. [Trump’s] very cordial, he’s a funny guy, and he’s from New York. He can take a punch.” May 12th 2016
So looks like BK's in good company when it comes to changing your view on Trump!
