The outcome does not change anything for Democrats in their calculus for retaking the House in next November's midterms. They still need to pick up 17 seats.
Political handicappers consider that a tall order, considering the shrinking number of competitive congressional districts nationwide.
Jolly served as a former general counsel for Young and also worked as a lobbyist.
"Tonight brings an end to this election," a victorious Jolly told supporters. "Tomorrow provides the opportunity for us to embark together on a new journey of representation here in Pinellas County."
Sink, the former Florida Chief Financial Officer, narrowly lost the 2010 gubernatorial election to Rick Scott.
She conceded the contest more than an hour after the polls closed, expressing pride in her campaign and thanking volunteers and supporters.
"I have congratulated David Jolly and wish him the best success in representing the voices of Pinellas in Congress," she said.
Florida-13 is a swing district in a swing state. It covers most of Pinellas County between Tampa Bay and the Gulf of Mexico, including parts of St. Petersburg.
This is a district that voted Young pretty handily in 2012, but also helped President Obama win the state in his re-election. Republicans are already saying this portends absolute doom for the Dems in 2014, but unless the GOP plans to help run glibertarian douchebags like 27-year old Overby in all the competitive districts to split the youth vote, it's not indicative of the country as a whole.
On the other hand, Jolly has to now immediately defend the seat in November, and I'm betting 8 months of doing nothing by voting against Obamacare isn't going to get him the win when turnout should be higher than the 39% this special election brought around.
