Pro-Scott super PAC cancels fall TV ads as campaign struggles to gain traction

The super PAC supporting Tim Scott canceled its fall TV ad spending due to his low poll numbers.
Scott has struggled to gain traction in the Republican primary dominated by Trump.
The super PAC will redirect funds to grassroots efforts like door-knocking.
Scott's fundraising has lagged behind other candidates like DeSantis and Haley.
Without a surge in support, Scott's path to win the nomination remains uncertain.
