Flake is ahead of Carmona, but that could change depending on the uncounted ballots.

Arizona’s strict new voter ID laws meant that more provisional ballots were handed out on Election Day — Arizona Democrats have said the number of provisional ballots were higher in Hispanic neighborhoods.

Arizona law gives election officials 10 days to verify and process provisional ballots, giving them until Friday to finish counting the votes.

Last week, the Supreme Court agreed to hear arguments on whether the Arizona voting laws violate the Voting Rights Act.

“In light of the Supreme Court’s decision to hear challenges to the Voting Rights Act, we are reminded that the right to vote is the foundation of our democracy,” Reid said. “That right is not secure when some votes are counted while others are suppressed or ignored. I expect state and local officials in Arizona to ensure that every vote is counted promptly, accurately and equally.”
