Trump’s best numbers came in Wyoming and West Virginia; his worst numbers were in the District of Columbia and Vermont.

A majority of voters in 12 states approved of Trump’s job performance, while a majority disapproved in 27 states.

In the latest data from Morning Consult’s Trump Tracker , which measures the president’s approval rating in all 50 states and the District of Columbia, a record low of 40 percent of voters approved of Trump and a record-high 55 percent disapproved, resulting in the worst monthly net rating of his presidency. The latest data is based on 156,104 surveys conducted Jan. 1-31.

At the start of a new period of divided government and amid the longest government shutdown in U.S. history, President Donald Trump’s popularity found a new floor in January.

The nadir was largely fueled by record opposition outside of the president’s base: 88 percent of Democrats and 56 percent of independents disapproved of Trump during the first month of 2019, the most of any month since his Jan. 20, 2017, inauguration.

Trump’s base remained fairly solid, with 83 percent of Republicans approving of the president. But that share of support among Republicans was its lowest since September, when Washington was roiled by the Supreme Court confirmation proceedings for Brett Kavanaugh.

The poor national marks were reflected at the state level.

A majority of voters in just 12 states approved of Trump’s job performance, all of which were red enclaves spanning from Wyoming to Alabama. The president retained support from a plurality of voters in five other states he easily carried during the 2016 election: Alaska, Indiana, Kansas, Montana and North Dakota. But another state that Trump won, Nebraska, was split.
