Turnout is much lighter than two years ago. But voters at the one polling site in Aberdeen have a lot to say.
"The issues are we still going to have the annexation or what? Most of these guys stand for one side or the other," said voter Jimmy Brown.
Development is a top issue. Two years ago, Mayor Mike Bennett beat out the incumbent mayor and now City Council President Mike Hiob is hoping for the same success.
The candidates take a different stand on how Aberdeen should grow in the coming years.
"My goal is to build our commercial base in the city. A healthy city has about 25 percent of their tax base in commercial. We have about 5 or 6 percent," said Mayor Bennett.
"Guess what - we have commercial stuff sitting around waiting to be built. What are they waiting on? Two things - the economy and the roof tops to make them viable," said City Council President Mike Hiob.
Over the next four years, Aberdeen and the nearby cities will see a population boom.
Under BRAC, up to 40,000 new jobs are expected within just five miles of Aberdeen proving ground. How to handle all those people is at the center of this year's mayoral race.
Aside from continued development, former state delegate and Harford County councilwoman Barbara Kreamer has made property taxes her platform.
"Since 2005, tax bills for Aberdeen residents have risen almost 100% and people really need a change," said Kreamer.
Whoever gets the non-partisan seat will lead the city through some of its biggest changes as more people come to work and live in Aberdeen.
There are seven candidates running for the four city council seats.
Polls stay open until 8 p-m.
