New ad testing from Blue Rose Research shows that LCV Victory Fund’s “Incredible Deal” ad, which is running in AZ-06, IA-03, MI-07, MN-01, VA-01, and WI-03 determines that the ads increased unfavorability for Republicans by 8 percentage points and moved vote choice towards Democratic candidates by 4.7 percentage points. The ads focused on incumbent Republicans in those districts who took data center-linked donations, voted to give billions in tax breaks to data center developers and left their voters with polluted local water and rising energy bills.
