Everyone is watching Democratic candidate Jon Ossoff today.The 30-year-old is challenging political veteran Karen Handel, who used to be Georgia's secretary of state, in a special election for the state's 6th Congressional district.
The election is seen as the first major referendum on Donald Trump's presidency because the district typically leans Republican. If Ossoff wins, the 2018 midterm elections could look ominous for Republicans.
See how a neophyte who's never held office became one of the most talked-about politicians of 2017.
