Texas Senator Ted Cruz refused to say the effort to defund Obamacare failed or is finished as he talked to nearly 600 people at the Republican Party of Iowa's annual Ronald Reagan Dinner.
"None of us thought taking on the Washington establishment was going to be easy," Cruz said, "none of us thought this was going to be a simple path. We all understand it was going to be an ongoing effort and right now, I am more encouraged than ever."
Cruz called out fellow Republican senators for failing to back efforts to get Congress to take away all funding for President Barack Obama's signature piece of legislation, the Affordable Care Act.
The gridlock led to the partial shutdown of the federal government for two weeks. Cruz maintains the effort demonstrated the strength of the grassroots.
He cited #MakeDCListen, the Twitter's hashtag, that got sent a million times over 30 days. Cruz argued that proves he's part of a change in American politics, giving the power to the people.
He said, "I'm convinced we're facing a new paradigm in politics. It is a paradigm that is the rise of the grassroots. I gotta tell you it has official Washington absolutely terrified."
Tickets for the event ranged from $100-1000.
