A poll shows a continued decline in active-duty service members’ views of President Donald Trump and a slight but significant preference for former vice president Joe Biden in the upcoming November election. The results, collected before the political conventions earlier this month, appear to undercut claims from the president that his support among military members is strong thanks to big defence budget increases in recent years and promised moves to draw down troops from overseas conflict zones. But active-duty troops and the Institute for Veterans and Military Families (IVMF) have seen a steady drop in troops’ opinion of the commander-in-chief since his election four years ago. The dipping popularity among troops - considered by Republican Party leaders to be part of the base of Trump’s support - could prove problematic for him, as there is significant disagreement among active-duty respondents about several recent controversial presidential policy statements.
