Dallas County’s request for a recount of last week’s election after it discovered a discrepancy between the number of voters who signed in and the actual ballots counted will be heard by a district court judge on Tuesday. The county’s election chief, Toni Pippins-Poole, filed a request to reopen the election late Friday after ballots from 44 vote tabulating machines were not included in the final tally that officials had submitted, according to court papers. Without knowing how many votes are at issue, it’s unclear whether the outcomes of any races will change. State law stipulates that ballots must be counted continuously after the polls close. Once officials have stopped tallying votes, the election is considered completed. Even though the results are unofficial until county commissioners approve them, a judge must order any additional ballot counting. Judge Emily G. Tobolowsky will consider the recount request. Between the two parties, more than 317,000 ballots — 233,014 Democratic and 83,997 Republican — were counted last week, according to unofficial results on Dallas County’s election website. Democratic turnout, in particular, nearly hit a record — second only to 2008 when 298,612 Democrats voted.
