Pro-Israel lobby spending millions to help unseat Massie in history's most expensive House primary

The pro-Israel lobby has spent millions on an effort to unseat Rep. Thomas Massie in the Kentucky Republican Primary on Tuesday, making it the most expensive House primary on record.

Pro-Israel interest groups have dropped $9 million into the effort, and prominent Republican pro-Israel donors spent millions more on a super PAC supported by President Donald Trump's political operations, which has spent $7 million on the race. Altogether, spending on the race has topped $32 million, according to Politico, which cited figures from AdImpact.
