How we got here
The Louisiana Senate seat opened after Bill Cassidy, who voted to convict Trump, was defeated in the May primary. Letlow, who entered the race in January with Trump’s endorsement, led in most parishes and secured a decisive win in the runoff, with support from Governor Jeff Landry and House Majority Leader Steve Scalise. Fleming remained a staunch MAGA advocate and challenged Letlow with a conservative platform.
