Former Wisconsin Gov. Tommy Thompson, a Republican elected to four terms starting in the 1980s, announced Monday that he will not run again in a bid to take on the Democratic incumbent in the battleground state.
A campaign by the 80-year-old Thompson would have put him on the ballot for the first time in a decade and 24 years after his last win. The winner of the Aug. 9 Republican primary will advance to face Gov. Tony Evers.
