Republicans have been more vocal in taking on some their own regarding where they stand on foreign policy.
With today's terrorist attacks in France have begun to raise questions of how Hillary Clinton would handle foreign policy.
"Hillary Clinton, for better or worse, was a more militaristic member of the Democratic party. And that was not to her advantage in 2008, and I am assuming that entrants into the Democratic primary in 2016 would like to remind voters of that," the Huffington Post's Sam Stein said.
While this weakness among liberals could hurt Clinton, she still has a massive vulnerability to attacks from the right. Having served as Obama's Secretary of State, she will be tied to the plethora of the administration's failures in foreign policy.
