A new poll found that 64 percent of respondents oppose the Trump administration’s decision to partially support a lawsuit that aims to gut Obamacare.

The poll from the Democratic-leaning firm Public Policy Polling was released Monday on the one-year anniversary of the defeat of Obamacare repeal in the Senate, and provides insight into why Democrats have hammered the administration over the lawsuit, even making it part of their attacks against Supreme Court nominee Brett Kavanaugh.

Texas and 19 other states charge in a federal lawsuit that as an indirect result of last year's repeal of the penalties for going uninsured, Obamacare is no longer constitutional and must be struck down.

The Department of Justice decided to not defend Obamacare in court and supported the lawsuit in part. But the DOJ stopped short of saying the entire law should be struck down, saying instead that only the law’s regulations related to requiring insurers to cover those with pre-existing conditions needed to fall.

The poll found that 64 percent of people oppose the decision by the administration and only 19 percent support it.

The poll also found more support for a generic Democratic candidate for Congress who supports Obamacare (56 percent) compared with a Republican candidate for Congress who wants to repeal it (40 percent).

Public Policy Polling surveyed 514 voters and the poll had a margin of error of 4.3 percentage points.
