Ted Cruz had to counteract the growing narrative his campaign is using “dirty tricks,” but his decision to fire spokesman Rick Tyler may make the problem worse, Charles Krauthammer said tonight.

“I understand how the Cruz campaign felt,” Krauthammer said on Monday’s Special Report. “It had to do something to counteract this narrative because in these campaigns, these narratives, you don’t have to have them last for a year, six months, they go so fast, if you can create a narrative — a bad one about another candidate — that lasts three weeks, it can kill them.”

But firing Tyler “highlighted the issue,” Krauthammer said. “You fire a guy, it’s the main news story all of us are talking about. It’s the lead story, it gives, of course Trump and Rubio an opportunity to pile on with those rough tweets. I’m not sure he’s cured this problem at all.”
