On Fox News this morning, Karl Rove weighed in on reports of Michele Bachmann's migraine problem.
"For the Bachmann campaign, this is the first big challenge.
It's evidence of what happens when you jump up into the top ring of these polls, and the kind of scrutiny that you get.
It's going to be important for her to get her doctors out there quickly to provide medical records and to provide the reassurance that people are going to want to have that this is not a serious issue."
Earlier this week, the Daily Caller published an incendiary story, inspired by anonymous critics who suggested that her headaches made her unfit to be president.
Bachmann later released a statement, admitting that she takes medicine for migraines, but claiming that it hasn't affected her capacity to lead.
