But the most effective messengers for the presidential candidates are not their running mates.

Together with our partners at SSRS survey research firm, ABC News asked Americans how much they are influenced by the Republican and Democratic candidates' surrogates on the campaign trail and which high-profile supporters of the candidates are the most effective messengers.

Similarly, just 14 percent said Trump's running mate, Indiana Gov. Mike Pence, is the strongest messenger for the Republican presidential nominee.
