Party affiliation predicts support for deploying US ground troops.

Evidence

Former architects of the Iraq war and their supporters clamored for U.S. deployment of ground troops to Iraq and Syria. However, the public was deeply divided along political lines on this issue, with 57% of Republicans favoring troop deployment but only 39% of conservative and moderate Democrats and 27% of liberal Democrats supporting it (Growing support for campaign, 2015). — Albert Bandura, Moral Disengagement, 2493
