Months of ads from candidates and PACs have produced little change in poll results for the Republican primary. Meanwhile, Trudy Busch Valentine is the only candidate in the 11-person Democratic field with ads on the air.
In late March, a poll from Trafalgar Group showed the Republican Senate primary in a dead heat.
U.S. Rep. Vicky Hartzler, with 24.9%, held a slight edge over former Gov. Eric Greitens, with Missouri Attorney General Eric Schmitt just behind but all within the 3% margin of error.
Three months later, after nearly $10 million of television ad spending along with radio and social media buys, little has changed. In the polling firm’s latest survey, completed June 30, Hartzler had 24%, slightly ahead of Greitens, with Schmitt within the 2.9% margin of error.
