Nevada Sen. Dean Heller’s Republican primary challenger is trying to tie him to Ivanka Trump as a way to cast him as too liberal.

Danny Tarkanian, in a local radio interview on Wednesday, invoked the first daughter’s politics in an attempt to undercut Heller’s claims of strong working relationships with President Donald Trump and Ivanka Trump.

“Dean Heller’s saying that he talks to Trump on the phone all the time; talks to Ivanka Trump all the time,” Tarkanian told KBET host Kevin Wall. “Well, Ivanka Trump was a Democrat, and she’s very, very moderate to liberal, compared to the Republican base.”

By casting the first daughter as out of touch with conservatives, Tarkanian demonstrated his effort to capture voters who bought into Trump’s campaign pledges and are loyal to the President, but suspicious of those around him in Washington — particularly on Capitol Hill.
