Politico reports today that Fox News contributor John Bolton's recent media blitz “comes as Bolton is mulling a run for the White House.” Politico noted:

The former United Nations ambassador appeared on the cable network at least 15 times between Jan. 31 and Feb. 4 to discuss the political turmoil rocking the foreign policy world. That's more than double his number of appearances during the week before.

Last year Media Matters calculated the monetary value of the airtime given to various GOP presidential candidates who are on Fox News' payroll, valuing Bolton's then 36 Fox News appearances at just under $3 million.
