By a Republican Minnesota state senator, in 1903.
But, did Stephens steal it from Saunders Norvell?
To Google.
Stephens was a state senator from 1903-1910 (link).
Norvell, a Democrat, used the slogan when running for city council and/or mayor in St. Louis around 1913 (link).
So, checkmate for Stephens.
Plus the unnecessary quotation marks on Norvell"s button are embarrassing.
