Palin's father Chuck Heath has long supported Tarkanian, one of the many Republicans hoping to unseat Senate Majority Leader Harry Reid this November.
"You supported my daughter Sarah Palin, now please join me in supporting another strong conservative – Danny Tarkanian," Heath says in the state-wide ad, according to a script provided by the campaign. "Danny Tarkanian is strongly pro-life, and he will protect our Second Amendment rights. He will fight to cut taxes, slash spending, and end budget-busting pork barrel politics."
The retired science teacher who lives in Alaska made five stops across Nevada last October with Tarkanian, the son of legendary college basketball coach Jerry Tarkanian. A recent Mason-Dixon poll shows Tarkanian trailing Nevada GOP chairwoman Sue Lowden by nearly 20 points. The survey also showed Lowden leading Reid by 13 points and Tarkanian leading the Senate's top Democrat by 11 points.
Palin herself has not endorsed a candidate, thought she will be on hand for a Tea Party event later this month in Reid's hometown of Searchlight, Nevada.
The primary will be held on June 8.
