Obama has given up on his surgeon general nominee, a Dr. Vivek Murthy, who is anti gun, and considers gun ownership a disease. NRA said a vote in favor of Murthy would be reported to the membership, a serious threat. NRA has some 5 million dues paying members, it gets the word out to the membership via a monthly magazine, American Rifleman, and the membership takes a word from the NRA very seriously, far more seriously than they take a word from the MSM.
Anyhow, nervous democrats from red districts decided that voting for Obama's surgeon general might get them voted out of office in November. There were enough democrats seeing the light that Obama has given up on the nomination.
