SurveyMonkey polling from the first week of February shows a similar pattern: 89 percent of Republicans1 said they approve of Trump’s handling of his job as president. And the share of Republicans who “strongly approve” — in the mid-50s for much of last year — is up to 61 percent.

It’s not totally clear why Trump is getting a boost among Republicans. Perhaps positive economic news has brought some wary GOP voters home. Perhaps Republican partisans are happy that Trump and the GOP-controlled Congress passed some major legislation. But that increased support is showing up in Trump’s overall approval rating. It was stuck in the high 30s for a lot of last year but is now in the low 40s.
