Former President Barack Obama's decision to directly criticize President Donald Trump will result in "60 days of rage" leading up to the 2018 midterm elections, Axios reported Saturday.

On Friday, Obama called out Trump by name for the first time since the leadership transition.

"The state of play: Republican lawmakers would love to talk about the growing economy. House Democrats have a high-minded closing argument, 'For the People,'" Axios noted. "Good luck breaking through with either of those."

Obama's return to the campaign trial got into President Trump's head and is worrying GOP strategists.
