Alex Sink, who lost a key special election in Florida last month, has opted not to challenge newly minted Rep. David Jolly (R-Fla.) again in November.

The former Florida chief financial officer and 2010 nominee for governor made the announcement Tuesday morning.

“I am so honored and humbled by the outpouring of support our campaign received, but after reflection with my family I have made a personal decision not to run for the 13th Congressional District seat in the 2014 election," Sink said in a statement. She added:"I remain totally convinced that a Democrat can and will win this congressional seat in the fall, and I look forward to helping the Democratic nominee."

Sink's decision not to run leaves Democrats in a tough spot, trying to recruit for a top-tier race with less than seven months to go. Jolly, meanwhile, will likely benefit financially from his newfound incumbency.

Democratic Congressional Campaign Committee Chairman Steve Israel (N.Y.) notably lobbied for Sink to try again following her loss.

Israel insisted Democrats will make a run at the newest congressman, though.

"Pinellas residents have voted time and again for commonsense solutions instead of reckless partisanship, which is why we are confident our Democratic nominee can prevail on Election Day," he said.

Republicans hailed Sink's decision as a sign that Democratic candidates don't feel good about their chances in November.

“Washington Democrats can’t even convince their die-hard career politicians to walk the plank this November," said Katie Prill, a spokeswoman for the National Republican Congressional Committee.
