A nascent effort to resurrect Obamacare repeal this year in the Senate is running into the same roadblock that stymied efforts last year: not enough GOP support.

Sen. Lindsey Graham, R-S.C., said he is working on a new repeal bill that could come out in “hopefully the coming weeks, not months.” Republicans could be blamed for premium increases on Obamacare’s exchanges in 2019 if they don’t act to repeal the law, he said.
