In contrast, throughout the entirety of 2015 — a non-presidential election year — there were about 10,500 new registered voters in Onondaga county, Czarny said.
Czarny said that because of excitement that circulates during the presidential election year, people are driven to vote. The numbers of those arriving on Election Day in Onondaga County may more than triple this year compared to a non-presidential election year, according to CNY Central.
