Former Alaska Gov. Sarah Palin (R) is jumping on the push to defund ObamaCare by threatening a government shutdown. 

Palin urged lawmakers to demand that a government funding bill include no funding for ObamaCare in an email sent out by the Senate Conservatives Fund, a group running ads pressuring Republican senators to back the effort.

"The time for rhetoric and ceremonial votes in Congress is over," Palin wrote in the email. "The time to take serious action to stop Obamacare is now. Join us in urging Senators — Don't Fund Obamacare! Just remember — if you fund it, you own it!"

Palin remains popular among grassroots conservatives and her support could fuel additional Tea Party backing for the defund ObamaCare position.

But other Republicans are sounding the alarm bells about the strategy, arguing the GOP will be blamed for a shutdown. 

Some even argue forcing a shutdown would be the only way Republicans could lose their House majority next year.
