President-elect Joe Biden’s lead over President Trump in Arizona fell below 15,000 votes as of Monday, but the president is unlikely to stage a successful comeback in the key battleground state.

As of Monday night, Biden had a 14,746-vote lead over Trump after the president took a slightly higher percentage of votes in the latest results out of Maricopa County, the Arizona Republic reported.

However, the president received just over 49 percent of those votes. He would need to secure more than 60 percent of outstanding ballots statewide to catch up to Biden.

Roughly 63,000 votes remain uncounted in Arizona as of this week, according to the Republic’s estimates. A majority of the uncounted votes are from provisional ballots, which are used when a voter is unable to verify their identity at a polling center. Just 54 percent of the provisional ballots cast in Maricopa County so far were deemed valid and added to a candidate’s total.

The Fox News Decision Desk projected a Biden victory in Arizona on Nov. 3, handing the former vice president 11 electoral votes and flipping a state that Trump carried in 2016.

The Trump campaign pushed back on the call. Officials argued the state was called for Biden prematurely because too many votes had yet to be counted.
