Rodolfo Hernandez, a septuagenarian construction magnate and former mayor, is enjoying a late rise in polls ahead of Colombia's presidential vote on Sunday, boosted by his colorful social media presence and anti-corruption promises.
The ex-mayor is currently running third, but within striking distance of the center-right's Federico Gutierrez. If he manages to make it to a likely second round, surveys show he would be only a few points behind leftist front-runner Gustavo Petro.
