On the other hand, Cruz thinks his message and background perfectly resonate with the GOP electorate in the Lone Star State. On the campaign trail, he touts his experience battling federal overreach as Texas' attorney before the Supreme Court. He rails against the policies of President Obama, whom he regularly refers to as the most radical president in the country's history.
Armed with what he believes to be a superior campaign message, Cruz sees Dewhurst's deep coffers as the main roadblock to a primary upset. If Cruz can compete financially and get his message to voters via television ads, he believes he will come out on top in the polls. He says he doesn't need to raise as much money as Dewhurst, just enough to get on the air statewide.
And so far, Cruz is pleased with his fundraising efforts. He raised more than $1 million in the first quarter of the year and nearly $800,000 in the second quarter. Cruz said they had a "very strong" third quarter. The campaign expects to release the details of its latest fundraising report this week.
Cruz also will receive a financial boost from his growing national profile. He has been endorsed by FreedomWorks, the Club for Growth and Sen. Jim DeMint's, R-S.C., Senate Conservatives Fund, all of which are expected to raise money for his campaign.
Last cycle, DeMint butted heads with Sen. John Cornyn, R-Texas, the head of the National Republican Senatorial Committee, in several Republican primaries. But the NRSC is staying neutral in contested GOP primaries this time around, and Cruz said it seems relations have improved between the two colleagues.
"I am encouraged that Sen. Cornyn and Sen. DeMint by all appearances are working well and closely together," Cruz said.
While he sees the race as a two way contest, Cruz said the presence of former Dallas Mayor Tom Leppert could further boost his chances at beating Dewhurst. Leppert has faced criticism for his moderate mayoral record, but he has shown the ability to raise funds and spend his own money on the race.
"Mayor Leppert draws moderate and liberal Republicans away from David Dewhurst, which is unambiguously helpful," Cruz said. "I think he plays the role of Ralph Nader to David Dewhurst's Al Gore."
While that analogy might make him George W. Bush, Cruz doesn't expect any recounts will be necessary. If he is able to raise enough money to compete with Dewhurst, Cruz said he expects to win "overwhelmingly."
"On election day, David Dewhurst will be a 67-year-old incumbent establishment politician with a decade of compromises behind him, who has never in his life been to a tea party," Cruz said. "In 2010, the number of candidates with that profile who won a contested Republican primary for Senate nationwide was zero. It is almost a political perfect storm of the wrong candidate with the wrong record running at the wrong time."
