The national opinion poll, which ran from Jan. 1 to Jan. 7, found that 51 percent of adults believe Trump “deserves most of the blame” for the shutdown, which entered its 18th day on Tuesday. That is up 4 percentage points from a similar poll that ran from Dec. 21 to 25.

Another 32 percent blame congressional Democrats for the shutdown and 7 percent blame congressional Republicans, according to the poll. Those percentages are mostly unchanged from the previous poll.
