Insurgent challengers fell flat in Florida on Tuesday as Republican US Senator Marco Rubio won his party's nomination to seek re-election in November and US Representative Debbie Wasserman Schultz held a big lead in her Democratic nominating race.
The non-traditional campaigns of Republican presidential nominee Donald Trump and US Senator Bernie Sanders, who exceeded expectations in his failed Democratic White House bid, gave rise to speculation other insurgent politicians could gain traction this year.
But that was not the case, at least in closely watched nominating races in Florida.
Rubio, who abandoned his presidential campaign in March, cleared the initial hurdle in his battle for a second six-year term in the US Senate. He defeated novice politician Carlos Beruff, a millionaire homebuilder, who embraced Trump.
