According to a poll from YouGov, just over half of the American public would support a deployment of ground troops to fight ISIS.
Democrats are divided on the question of ground troops while Republicans overwhelmingly support it. One of the primary reasons 53 percent of Americans support sending ground troops is that there are few alternatives.
Even though air strikes have stalled the momentum of ISIS militants in Iraq, less than one in four Americans believe the group can be defeated through air power alone. However, some good news has emerged from Northern Iraq over the past few days with news that government troops have forced ISIS combatants to flee Tikrit. A confident Iraqi military gaining momentum may well provide the American public with another alternative in the fight against ISIS.
This chart shows the percentage of people in the U.S. who support/oppose sending ground troops to fight ISIS.
