The Senate on Wednesday rejected a Democratic effort to roll back a Trump administration rule that allows states to ignore parts of ObamaCare.

Senators voted 43-52 on the resolution, falling short of the simple majority needed to pass the chamber.

Democrats wanted to overturn a Trump administration rule that makes it easier for states to opt out of certain ObamaCare requirements and prioritize cheaper, less-inclusive plans than ones offered under ObamaCare.

Members of the party have termed the plans “junk insurance” because companies can refuse to cover people with pre-existing conditions. 

“These are nothing but a boon to health insurance companies.

Democrats view health care legislation as a political vulnerability for Republicans after many voted for an unsuccessful attempt to repeal ObamaCare in 2017.

Democrats made protecting health care coverage a key part of their strategy to win back the House in 2018. They also view Wednesday’s vote as an opportunity to squeeze GOP senators in key 2020 Senate races including Collins, Cory GardnerCory Scott GardnerMark Mellman: Three questions for Republicans The Hill's 12:30 Report: White House official testifies he warned about Trump pressure on Ukraine The Hill's Morning Report - Presented by Better Medicare Alliance - Dems shift strategy on impeachment vote MORE (Colo.) and Martha McSallyMartha Elizabeth McSallyMark Mellman: Three questions for Republicans Kelly, McSally virtually tied in Arizona Senate race: poll The Hill's 12:30 Report: White House official testifies he warned about Trump pressure on Ukraine MORE (Ariz.).

“Senate Republicans never miss an opportunity to do exactly the wrong thing for their constituents on health care, and this vote will be no exception,” Democratic Senatorial Campaign Committee spokesperson Stewart Boss said in a statement.

Democrats are able to force a vote on the Trump administration guidance under the Congressional Review Act. However, they face a steep climb to picking up four GOP senators needed for the resolution to pass after a similar healthcare vote failed last year largely along party lines.

Republicans and the Trump administration have repeatedly said they will continue to protect people with preexisting conditions, while simultaneously advocating for ways to end ObamaCare.

A federal circuit court in New Orleans is expected to rule in the coming days or weeks on an administration-backed lawsuit to overturn the entire health care law.

“Democrats' resolution has zero chance of becoming law. This is just another political messaging exercise with no path to making an impact,” McConnell said.
