One local election prognosticator thinks Arlington could see record voter turnout for a gubernatorial election on Tuesday.

County Treasurer Frank O’Leary (D), Arlington’s unofficial predictor of local voting trends, says a dramatic increase in absentee voting this year points to higher voter interest in the Virginia governor’s race.

“This year’s race will probably set the record for turnout in a Gubernatorial Year,” O’Leary wrote. “In 2009, with seven days of voting remaining, 2,914 absentee votes had been cast. This year, 4,476 have already voted absentee and I expect the final number to hit 7,200 or more.”

O’Leary says the government shutdown might have boosted absentee voting.

“It seems likely that this remarkable increase in absentee turnout is a direct result of federal workers being furloughed,” he wrote. “During the furlough period, 500 additional votes occurred when compared to 2009. Those additional votes may well have arisen from angry federal workers, who had nothing better to do.”

O’Leary is predicting a total turnout of roughly 70,000 ballots cast among the 137,027 active registered voters in Arlington. That predicted 51.1 percent turnout rate in Arlington compares to 42.9 percent for the 2009 race between Bob McDonnell (R) and Creigh Deeds (D), and 50.5 percent for the 2005 race between Tim Kaine (D) and Jerry Kilgore (R).

(The turnout for presidential and congressional elections is generally higher than that of gubernatorial elections, with an average of 81.6 and 56 percent of active voter turnout respectively in Arlington between 1972 and 2012, according to O’Leary.)

Speaking to ARLnow.com on Tuesday, Arlington County Registrar Linda Lindberg confirmed the increase in absentee voting so far this year. She said absentee voting will “definitely” be higher than in 2009. She was more conservative in her prediction for overall turnout, calling for a 50 percent turnout rate.

In addition to various local races, Election Day on Nov. 5 will feature the hotly-contested Virginia governor’s race between Democrat Terry McAuliffe, Republican Attorney General Ken Cuccinelli and Libertarian Robert Sarvis.
