If Donald Trump's increasingly strong night turns into a win and he heads to the White House, the Republican Party will have a very real shot at repealing Obamacare, dismantling a system in a move that would leave 22 million Americans without health insurance coverage.
Republicans could easily retain control of the Senate. They're expected to keep the House. One party rule could mean President Obama's health care law will be in real jeopardy.
"They have a death blow to the Obamacare health coverage expansion," says John McDonough, a Harvard University professor who worked in the Senate on the passage of the Affordable Care Act.

Republicans began to lay serious groundwork against Obamacare last winter. In January, both the Senate and the House passed a reconciliation bill that took apart Obamacare's expansion of Medicaid and private, subsidized health insurance.
The bill didn't matter much at the time—Obama repealed it when it arrived at his desk—but it showed that Republicans could use the reconciliation process to take apart key Obamacare pillars, requiring a simple majority rather than the 60 votes needed to overcome a filibuster.
Trump has promised that repealing Obamacare would be his first act in office. All he needs to do is pull this ready-made Republican plan off the shelf
