Dems: GOP needs to 'get over it' on ObamaCare

This outcome appears unlikely given House GOP leadership's current strategy of foisting a defunding vote on the Senate, where Democrats hold a majority.

Lawmakers and groups affiliated with the Tea Party scheduled a rally on the Capitol's West Lawn to push for the toughest possible tactics.

"[Republicans] are scared to death that this law is going to work," said liberal advocate Brad Woodhouse at a press conference, "because it will destroy their entire view of government and destroy what they have run on for the past several years."

Rep. Rosa DeLauro (D-Conn.) was more blunt. To nods from the other Democrats, she told the GOP to "get over it."

"The House passed [ObamaCare], the Senate passed it, the president signed the law and the Supreme Court upheld this effort," DeLauro said. 

Woodhouse leads the group Americans United for Change. The Tea Party-led rally was scheduled to begin at noon.
