The main super PAC supporting Senator Tim Scott’s presidential campaign abruptly announced to donors in a memo that it was canceling millions of dollars in television ads it had reserved this fall, writing that Donald J. Trump’s strength was so ingrained among Republican voters that additional advertising would currently make little difference. “We aren’t going to waste our money when the electorate isn’t focused or ready for a Trump alternative,” Rob Collins, a Republican strategist who is a co-chairman of the super PAC, wrote in the blunt memo to donors that was circulated on Monday. The super PAC, called the Trust in Mission PAC, or TIMPAC, has been one of the largest advertisers in the race, spending roughly $5 million in Iowa alone this year. Mr. Scott’s poll numbers have hardly budged, however, and Mr. Trump remains far ahead. In addition to the super PAC, Mr. Scott’s campaign had also spent aggressively on television advertising, spending more than $12.5 million on ads to run through the end of November, the campaign said.
