Rep. Patrick Murphy is projected to win Florida’s Senate Democratic primary after one of the wildest primaries in the nation.

President Obama and Vice President Biden were among the top Democrats who endorsed Murphy in the primary.

Grayson faced pressure to end his campaign after domestic abuse allegations surfaced from his ex-wife last month. Several progressive groups retracted endorsements in the wake of the allegations.

Grayson’s campaign started to spiral after a New York Times investigation exposed emails with top staffers advising Grayson to close his hedge fund.

Murphy goes into the fall with lower name recognition than Rubio, a former Republican presidential candidate, and with a deficit in most polls.

Murphy will also have to overcome some of his own speed bumps that surfaced during the primary.

An investigation by CBS Miami found he overstated parts of his resume, and Republicans have hammered him for receiving significant financial backing from his father.

But political observers in the state expect a close race that could largely hinge on what happens at the top of the ticket.
