WASHINGTON (CNN) Support for impeaching President Donald Trump has fallen 7 points since December, a CNN Poll conducted by SSRS finds, following Speaker of the House Nancy Pelosi calling impeachment "so divisive to the country."

The decline -- from 43% in favor in December to 36% now -- stems largely from a change in Democratic views on impeaching the President. In December, 80% of self-identified Democrats said they were in favor of impeachment -- that now stands at 68%, a 12-point dip. Among independents and Republicans, support for impeachment has fallen 3 points over the same time.

The only major subgroup among which the decline was larger than among Democrats is college graduates: 50% backed impeachment in December, 35% do so now. Combining the two to look at Democrats with college degrees, support for impeachment fell 17 points from 79% in December to 62% now.

Despite Pelosi's comments, some members of the Democratic caucus in the House of Representatives have vowed to pursue impeachment this year.
