It is a FOX poll, but I think it's reasonably clear nonetheless that national security has hurt the Democrats somewhat.
It'll get better as the election season goes on. Hillary will become more aggressive on war plans in Syria/against ISIS once the nomination is wrapped up, and liberals will come home to her. It probably is a tossup against non object-able Republicans like Rubio and she'll lead nuts like Trump and Cruz by a healthy margin.
Not that there aren't polls that indicate this now, but it'll become more obvious in every poll as time goes on.
