"A similar failure to progress has also afflicted the nation’s social agenda. In areas such as public education, health and wellness, personal safety, water and sanitation, environmental quality, and tolerance and inclusion, among others, U.S. progress has stalled or gone in reverse. In these areas, where America was often a pioneer and leader, the U.S. has fallen well down the list compared to other advanced countries. Tolerance, inclusion, and personal freedom are registering troubling declines, a sign of growing divisions in our society."

REPUBLICANS are gutting public education
REPUBLICANS are determined to take HEALTH CARE away from virtually everyone but the wealthy
REPUBLICANS are trashing the clean water & air laws
REPUBLICANS are denying climate change
REPUBLICANS are oppressing, harassing and denying equal opportunity & human rights to PoC and women

ALL. REPUBLICANS.
