"I tried to go to (Ohio State University) one day since both candidates were having rallies there," Roberts says. "But I couldn't get close enough to comfortably walk. I'm so disappointed."
Which means, just days from this year's election, she still hasn't made up her mind.
"I'm close, real close," she says.
Instead, she must rely on the information that comes to her.
"Let me count," Roberts says, as she flips through her stack of mail. "I've got seven different political mailers just today."
She doesn't mind the mail, nor does she mind the calls -- except when there are so many they fill up her voice mail and her family can't leave a message.
"And I'd love to watch a game show without the 50 political ads," she says. "My sister complains she feels neglected living in Georgia. But the ads are so negative, I tell her she's lucky."
Roberts reads several newspapers to follow the campaign. She watched the debates closely.
"I think President Obama made a stand, finally with that second one, and I'm so glad. He sounded kind of tuned out before," she says. "Romney sounds wishy-washy saying one thing to one group and then one thing to another. I can't figure out some of the promises he made."
Romney's disparaging comments about the poor at an earlier campaign event disturbed her.
"What kind of ignoramus thinks people want government help? Sometimes they just need it," Roberts says. "My family isn't in that 47% now, but growing up we needed help. What would we have done without it?"
She's still concerned, though, about the president's effectiveness.
"You know, I'd hoped he'd make the economy better, and I do think he is sincere," Roberts says. "I think he has tried to be honest with the public, but I am still not sure if he can pull us out of this mess."
Several people in her Columbus circle have hoped to bring her around. Many parishioners at her church read about Roberts on CNN. One day, they surrounded her.
"I was coming out of Mass and a man who saw my story talked to me about why I should vote for President Obama," Roberts says. "Soon a crowd gathered and people kept saying things like, 'I know you have heard this and that, but don't believe it. Now I'm going to tell you the truth about him.'
"I always like when people start a sentence with, 'I'm going to tell you the truth.' I really start to listen then. But there wasn't any Romney supporter there. I would have liked the truth about him, too."
For now, Roberts will keep an open mind.
She already has Election Day plans. She and a neighbor like to be there right when the polls open and then go to breakfast. She signed up to be a poll watcher, too. Later she and her family will watch the returns at a sports bar.
"I like the multiple TVs and can get some wings."
Even if she hasn't quite made up her mind, for Roberts -- who grew up secretly encouraging African-Americans in the Deep South to register to vote during the height of segregation -- Election Day is still something to celebrate.
The Long-Term Unemployed: Casting an enthusiastic ballot
Joe Stoltz tuned in to the presidential debates listening keenly for specifics on how to improve the economy from both Obama and Romney.
But in the end, it was an exchange over something that happened thousands of miles away that helped turn Stoltz from undecided voter to one who felt secure in his choice.
In their second verbal tangle, Romney went after Obama by claiming that the president did not refer to the U.S. Consulate attack in the Libyan city of Benghazi as an act of terror and that the following day, he was back on the campaign trail.
Obama came back strong, Stoltz says.
