The investment comes as President Donald Trump attempts to brush off a string of primary losses, with his 10th endorsed candidate losing last week.

Graham Nordone is seeking the full term for the seat left open after her brother's sudden death, and Trump has endorsed her in the race.

As Trump rallied Friday evening for the appointed senator seeking a six-year term, it was clear she hadn’t won over some segments of the MAGA base who could be decisive.

While Graham's ad strategy may come across as being late to the punch, it follows the strategy Trump revealed he prefers to use in elections.

A Republican strategist said Trump is coming to her state to “seal the deal” for Graham Nordone and test "whether or not he can do that."

The Trafalgar Group survey shows Graham Nordone barely leading Norman, with 47.9% to 47.8%.
