Trump's support among his base is collapsing

President Donald Trump's support continued to slip with his core base of support over the past few weeks as his topline approval ratings hit new lows in multiple polls.

A Politico/Morning Consult poll out on Wednesday found Trump's approval at a new low in that poll, with 40% approving of his performance as president.

But as Politico points out, the percentage who approve strongly is just 18%, down from 22% in May.

The poll was conducted online between August 3 and 6. It surveyed 1,992 registered voters, and had a margin of error of plus or minus two percentage points.

Politico's poll came after a CNN poll released on Monday showed the president's approval rating at 38%, compared to 56% who disapproved. In that poll, 24% of respondents said they strongly support the president's performance, down from 33% who said the same in January after Trump took office. The telephone poll surveyed 1,018 adults, and had a margin of error of plus or minus 3.6 percentage points.

Trump has repeatedly broken records for low approval ratings in his first several months in office, becoming the most unpopular modern president at his six month mark, skipping the honeymoon approval period most presidents tend to experience in their first several months in office.

The Real Clear Politics average of recent polls - which did not include including Wednesday's Politico/Morning Consult survey - showed Trump's approval rating at 37.9% support, while data website FiveThirtyEight's approval tracker showed his support at 36.9%.

Trump's approval rating dropped to a new low in his coveted Rasmussen tracking poll, which the president has praised despite its more dubious reputation among polling analysts.

Following the round of recent polls reflecting Trump's slipping support, the president has resumed his time-tested campaign tactic of questioning the validity of the polls.
