“We’re talking about an issue that unites Democrats and cracks the Republican base right down the middle. This is just awful politics for Republicans,” he said.

As the Dec. 31 deadline looms to avoid soaring insurance premiums for tens of millions of Americans, the House GOP introduced a health care plan on Friday that did not include the soon-to-expire ACA subsidies, a key battle in the recent government shutdown.

House GOP leaders are expected to allow a vote on an amendment to extend the ACA subsidies next week, though the extension remains unlikely to pass as Democrats seek a clean three-year extension.

“We are seeing massive, massive majorities blaming Trump, saying they want the ACA subsidies to be extended. And if they’re not, they are blaming the Republican Party and Donald Trump,” Enten said.

“The polling is rarely ever this clear. But on this issue, it is very much clear. This is an issue that hurts Republicans and very much helps Democrats.”
