no do not drop out. apoligize and move on.
It isn’t very effective to apologize for being stupid. His comments give legitimacy to the war on women theme the democrats are running with. It will cost republicans close races all across the country. There will be more abortions because there will be more democrats elected. He needs to get out now. If he quits today or tomorrow the story dies. If he stays in, the republicans will get tarred with his stupidity every day until the election.
That’s exactly what most in the democrat party are saying too.
His exit is needed yesterday.
There is no moving on. Rape is the most charged word for women and what women fear the most.
