Nate Silver: “From the first full day of his presidency, Jan. 21, through yesterday — March 21: conveniently exactly two months later — Trump’s net approval rating has declined by 13.8 points, so around 7 points per month. A president can’t afford that rate of decline for long.”
G. Elliot Morris: “Although public opinion on Trump has been slow to move before, today, the fact he is underwater is a product both a loss of support in his approve category as well as a consolidation of undecided adults into the disapprove category.
The fence-sitters have mostly jumped off and sided against the president, while his support has softened.”
