Washington (CNN) Two of the highest profile races in the country -- both in Florida -- are likely headed to a recount soon.

Sen. Bill Nelson's re-election bid is likely headed to a hand recount given that the incumbent Democrat now trails Florida Gov. Rick Scott by 17,000 votes, within the .25% margin required for a hand recount. Nelson's campaign aides believe he will emerge victorious once all the ballots are counted.

And on the governor's side, Democrat Andrew Gillum -- after conceding the race on Tuesday evening -- has grown more supportive of a recount of late, in part because his deficit to Republican Ron DeSantis is down to 38,000 votes, within the .5% needed for a machine recount. Campaign aides, though, remain clear eyed about the the long odds that Gillum can make up that deficit.

Recounts, which have not officially been authorized in either race, put the outcome of two of the most closely watched races of 2018 on hold, with Democrats hoping for a miracle that could get both Gillum, a candidate who garnered considerable attention in his campaign against DeSantis, and Nelson, an incumbent who Democrats had thought would win his seat going into Tuesday night, over the finish line with a win.

"On Tuesday night, the Gillum for Governor campaign operated with the best information available about the number of outstanding ballots left to count. Since that time, it has become clear there are many more uncounted ballots than was originally reported," Gillum's communications director Johanna Cervone said in a statement. "Mayor Gillum started his campaign for the people, and we are committed to ensuring every single vote in Florida is counted."
