OKLAHOMA CITY (AP) — Voter registration in Oklahoma has reached an all-time high following the November mid-term election.

The Oklahoma State Election Board's annual Jan. 15 voter registration count eclipsed 2.1 million, the Tulsa World reported .

"Our state saw a big increase in voter engagement in 2018, and I am hopeful that this trend will continue through 2019 and into the 2020 elections," said Paul Ziriax, Secretary of the State Election Board.

Voter registration totals are usually the highest after a presidential election. The 2017 voter count, taken two months after the 2016 presidential election, put total registration at 2,161,881, which was roughly 35,000 more than this year's sum.

The last voter total stood at slightly over 2 million after the last mid-term election in 2014.

Republican and independent registrations have continued their upward trends in recent years. Independent voters increased by 27 percent and Republicans by 14 percent from 2015 to 2019. Democrats dropped 12 percent in the same period.

Libertarians, who became a recognized party in 2017, totaled 9,274.

Republican registration surpassed 1 million for the first time in the annual January count, at 1,008,775. While Democratic registration came in at 777,770, up roughly 8,000 from a year ago but more than 100,000 less than in 2015.

Oklahoma's voter registration rolls are continuously updated with new additions and cancellations. Inactive registrations are purged in odd-numbered years, causing visible dips in the counts taken in January of even-numbered years.
