Sen. Bernie Sanders “more than quadrupled his spending in Iowa during the third quarter, pouring almost a half-million dollars into the state,” the Des Moines Register reports.
“He still falls short of U.S. Sen. Ted Cruz, a Texas Republican, and former Secretary of State Hillary Clinton in terms of total spending this cycle, but Sanders’ third-quarter spending represents a surge for him as he continues to challenge Clinton for front-runner status in the race for the Democratic nomination.”
