WASHINGTON Since the Affordable Care Act s passage in 2010, repealing Obamacare has been the driving issue for the Republican Party.

GOP lawmakers voted to defund, change or repeal parts of the law at least 67 times while President Barack Obama was in office, and they promised voters that if they won control of the White House, theyd make the dream of full repeal come true.

Republicans received their chance in the 2016 elections, which handed the party control of both chambers of Congress and the White House. But they failed to get the job done last year as voters realized what theyd be losing and public opinion swung in favor of the law. The GOP has shown no signs of trying to take up repeal again this year.

Now, Republicans are giving up on Obamacare repeal as a campaign issue as well. Anti-Obamacare ad spending in the 2018 election cycle has plummeted compared to the same period in the previous three cycles, according to data compiled by Kantar Media/CMAG for HuffPost.
