Map shows how much Trump's approval ratings have changed in each state since he took office

• The polling firm Morning Consult releases monthly approval ratings for President Donald Trump in each state.
• The firm's most recent results showed Trump's approval having dropped in every state and Washington, DC, between his January 2017 inauguration and last month.

Nearly two years after taking office, President Donald Trump has gotten less popular in every state and Washington, DC, according to the findings of one polling firm.

The firm Morning Consult releases monthly approval ratings for Trump from each state.

In January 2017, the month Trump was sworn in to office, he was broadly popular across a wide geographic area. Trump had a negative net approval rating - the share of the population approving of his performance minus the percentage disapproving - in only six states and Washington, DC.

Unsurprisingly, some of Trump's highest approval ratings came from stalwart Republican states in the interior of the country and the Southeast, while his lowest net approval came from liberal bastions on the West Coast and in the Northeast, along with the crucial upper Midwestern swing states.

By this past December, Trump's net approval rating had declined in every state and the District of Columbia. Drops in net approval ranged from a modest 6 percentage points in South Dakota to a massive 36-point swing against the president in New Mexico.

Trump's approval rating was underwater in 29 states and the District, including every state won by Hillary Clinton in the 2016 election. Further, Trump had negative net approval ratings across the Midwestern swing states of Iowa, Wisconsin, Michigan, Ohio, and Pennsylvania as well as in the southern battlegrounds of Arizona, North Carolina, Georgia, and Florida.

Trump's approval ratings even saw modest declines across several regions of the country since Morning Consult's November 2018 release, with a fall in net approval in all but seven states. It's worth noting, however, that most of the changes since November were small and could be the result of normal statistical sampling error.

Here's where Trump stood in every state in December, according to Morning Consult:
