Americans are split over President Trump's performance in the first 100 days of his administration, grading his efforts sharply along party lines, according to a new survey.

When asked to grade "the job Donald Trump has done as President of the United States" over the past 100 days, with an A being "excellent" and an F being "failing," a Politico/Morning Consult poll conducted April 13-15 found 39 percent of registered voters grade Trump at an A or a B. On the other end of the spectrum, 37 percent gave the president a D or an F. Seventeen percent of respondents graded the president's performance at a C.

The poll's margin of error is plus or minus two percentage points.

While 72 percent of Republicans awarded Trump with either an A or B, only 14 percent of Democrats did the same. Conversely, 67 percent of Democrats rated the president's job performance at a D or an F, with only seven percent of Republicans agreeing.

Polarization manifests even more clearly at the most extreme ends of the spectrum as well. Trump received an F from 48 percent of Democrats and an A from 33 percent of Republicans. Three percent of Republicans rated Trump at an F, while only five percent of Democrats did the same.

Trump has done little to assuage the fears of his opposition since assuming office and these numbers reflect it. Given the generally high marks he received from Republicans, however, it does appear he's managed to at least please his own base.

That nearly 70 percent of all respondents graded the president on either side of a C, marking him in the A/B or D/F range, suggests most Americans have strong opinions on his performance.

Only six percent of respondents answered "Don't Know/No Opinion."
