Politico clearly screwed up yesterday, but the WSJ stuff could sink him or bring out more stories that don't stand up to scrutiny. And WSJ is harder than most to shrug off as the liberal media.
There is another angle to the WSJ story and that is that he appears to be lying about being named "the most honest student"...that is getting a lot of LOLs on social media today. The story is moving from one of scrutiny to mockery. At the very least this is going to deflate his GE polling, because most non Republicans really dont know much about Carson.
