Republican presidential front-runner Donald Trump received the endorsement Tuesday of conservative firebrand Sarah Palin, giving the billionaire businessman a potential boost less than two weeks before Iowa's kick-off caucuses.
"Media heads are spinning," the former vice presidential candidate said after taking the stage at a Trump rally at Iowa State University. "This is going to be so much fun."
Palin, the former governor of Alaska and 2008 GOP vice presidential pick, said that, with Trump as president, America would no longer apologize.
"No more pussy-footing around," Palin said.
The endorsement comes as Trump is locked in a dead heat with Texas Sen. Ted Cruz in Iowa. The two have been ramping up their attacks against one another as the election has neared.
In the statement announcing the endorsement, Trump's campaign described Palin as a conservative who "helped launch the careers of several key future leaders of the Republican Party and conservative movement." The statement also quoted Cruz as once saying he "would not be in the United States Senate were it not for Gov. Sarah Palin. ... She can pick winners."
Campaigning in New Hampshire, Cruz said, "Regardless of what Sarah intends to do in 2016, I will remain a big, big fan of Sarah Palin."
Palin endorsed Cruz in his 2012 Senate race and said as recently as last month that he and Trump were both in her top tier of candidates, making the endorsement a symbolic blow to Cruz.
Palin's remarks in Ames, Iowa, were signature Palin, combining the folksy charm and everywoman appeal that initially made her a GOP superstar with defiant taunting of a "busted" GOP establishment that she slammed for counting both Trump and herself out.
Palin offered her full-throated support for Trump and slammed President Barack Obama as the "capitulator in chief." Trump, she said, would be a commander in chief who would "let our warriors do their job and go kick ISIS' ass!"
She also took aim at the Republican establishment for "attacking their own front-runner" and offered a challenge to those who have suggested that Trump, whose positions on issues like gun control and abortion rights have shifted over the years, isn't conservative enough.
"Oh my goodness gracious. What the heck would the establishment know about conservativism?" she said. "Who are they to tell us that we're not conservative enough? ... Give me a break."
Trump, whose team had been touting a major, surprise announcement, praised Palin as "a friend, and a high-quality person whom I have great respect for" in a statement.
"We're going to give' em hell," he said after her speech.
Palin will also be joining Trump at two events Wednesday, including a rally in Tulsa, Oklahoma.
Palin was a virtual newcomer to the national political arena when 2008 GOP presidential nominee John McCain named her as his running mate. She has since risen to prominence as one of the most outspoken conservatives in the party. She signed on as a Fox News commentator after resigning as Alaska's governor in 2010, a job she held until last year.
Trump and Palin did not discuss how the endorsement had come about, but Trump's national political director Michael Glassner previously worked for her. Trump said earlier Tuesday that he doesn't typically put much stock in endorsements, but said of this one, "I think it could very well result in votes."
GOP consultant Kevin Madden said the timing will likely help Trump crowd out Cruz's message as the Iowa caucuses approach.
"I think it helps Trump overwhelm the news cycle with Trump coverage at a critical time," he said.
Madden also said Palin's support could help shield Trump from charges that his past positions make him too liberal to be the GOP nominee, "giving Trump some rhetorical cover from a conservative validator in the eyes of many grassroots conservatives."
But some rally-goers at Trump's event Tuesday evening said they weren't sure whether Palin's support would help Trump win over voters. Several referenced what they saw as her poor performance as a vice presidential candidate.
"I don't think it's going to be a detriment, but I don't think it's going to be a huge asset," said Stephen Freese, 56, of Burlington, Iowa, who works in construction.
"I don't think she's really credible anymore," said Bruce Dodge, 66, a retiree who lives in Ankeny, Iowa.
The event came a day after Palin's oldest son, Track, was arrested in a domestic violence case in which his girlfriend told police she was afraid he would shoot himself with a rifle. Track Palin was charged with assault, interfering with the report of a domestic violence crime and possessing a weapon while intoxicated in connection with the incident.
Earlier Tuesday, Trump received an endorsement from the daughter of movie star John Wayne.
Standing in front of a life-size, rifle-toting model of the actor in full cowboy gear, Trump accepted the endorsement of Aissa Wayne at the John Wayne Birthplace Museum in Winterset, Iowa.
"America needs help and we need a strong leader and we need someone like Mr. Trump with leadership qualities, someone with courage, someone that's strong, like John Wayne," she said.
