Furious Sarah Palin unloads on former pal Ted Cruz as a 'half-term' US senator with no achievements
Sarah Palin speaks to ABC's "Good Morning America"

Sarah Palin, who has been credited with helping launch Texas Sen. Ted Cruz's national career by endorsing him in 2012 has had a change of heart since throwing her presidential endorsement to New York billionaire Donald Trump.

Writing on Facebook, the former half-term governor of Alaska took a slap at Cruz -- who is shaping up to be Trump's last standing rival for the nomination -- by calling Cruz a "half-term" U.S. senator lacking in any semblance of legislative "success" since he traveled to Washington D.C.

In the course of her diatribe, she also described Cruz as a career politician while knocking him for calling Trump's fans "low-information voters."

"Calling GOP front-runner supporters 'low information' disengaged voters, Ted Cruz's insinuation reeks of all the reasons America knows 'the status quo has got to go,'" she wrote. "The arrogance of career politicians is something at which the rest of us chuckle, but Cruz's latest dig strays from humorous into downright nasty."

"Where's information on any Cruz success whilst in his short, half-term U.S. Senate seat, proving his resume's advantage over another career politicians's lawyerly executive inexperience that includes never having created a single private sector job," she continued before equating Cruz with President Barack Obama by adding, " but boasting of his constitutional law teacher creds? (Remember America experimented with that resume before; how'd that work out for the country?)"

Palin also took a dig at former nominee Carly Fiorina for flip-flopping on Cruz when she bestowed her endorsement on the Texas senator this week.

"Info on consistency with his big endorsement this week, as Carly tells it like it is so very recently? " Palin wrote, adding this quote from Fiorina: "Ted Cruz is just like any other politician. He says one thing in Manhattan, he says another thing in Iowa. He says whatever he needs to say to get elected, and then he's going to do as he pleases. I think people are tired of a political class that promises much and delivers much of the same."
