Both Republican presidential candidate Mitt Romney and Republican vice-presidential Candidate Paul Ryan will make stops in southwestern Ohio on Tuesday to stump for votes as election day looms closer.

Ryan will host a “Victory Town Hall” at Byer Steel Group, 200 W. North Bend Road in Cincinnati. Doors for the town hall open at 9 a.m., with the event scheduled to start at 11 a.m., according to the Romney/Ryan website.

Ryan and Romney will appear together at a victory rally at the Dayton International Airport in Vandalia. Doors open for the event at 12:30 and the event starts at 2:30 p.m.

All attendees will go through airport-like security and should bring as few personal items as possible, according to the website. No bags, sharp objects, umbrellas, liquids, or signs will be allowed in the venue. Cameras are permitted.

Both Republican and Democratic presidential candidates are heavily targeting Ohio with money, advertisements and personal visits because Ohio is viewed as a key “swing state” with the winner still undecided.

“Ohio is a very competitive swing state and the second largest swing state next to Florida in terms of its 18 votes,” said Patrick Miller, a political science professor at the University of Cincinnati. “There aren’t a lot of states that are realistically up for grabs.”

Obama has maintained a “small but persistent” lead in the state among polls, with anywhere from a 2 percent to 7 percent majority, Miller said.

“If it was just one poll, you could say it was just a fluke, but he’s maintained that small lead,” Miller said. “It’s not insurmountable for Romney, but at the same time, thus far he’s been unable to gain real traction in the state.”

The primary focus for voters remains the economy.

“In every poll, voters put some sort of economic issue at the top issue,” Miller said.

On Wednesday, President Barack Obama will be in northern Ohio, campaigning in Bowling Green, Toledo and Kent.
