Cruz, appearing on "Fox News Sunday" just days after scoring a solid victory in the Texas Republican primary for the U.S. Senate, said support for the Tea Party is increasing exponentially.
"I think this was part of a tidal wave that began in 2010 and I think that tidal wave is only stronger in 2012," Cruz said.
Cruz said he is conservative and he thinks he reflects the values of most Americans.
"All across the country, the rest of Americans are looking at Washington and saying, what's wrong with you people?" he said.
"The principles that I think voters are looking for are not that complicated. It's live within your means, follow common sense principles, don't spend money you don't have. And that's what American people are standing up and demanding right now."
Cruz predicted Republicans will rally behind likely presidential standard-bearer Mitt Romney because "I think the absolute highest priority in the country in November is to defeat Barack Obama. And I have spoken to literally thousands and thousands of Tea Party activists. I have yet to meet a single Tea Party leader that is not going to vote for Mitt Romney and work for him because our country is in crisis. And we've got to stop this Obama agenda if we're going to preserve opportunity for our kids and grandkids."
