The John Edwards trial will head into a third day of deliberations on Tuesday.

So far, jurors have spent more than 10 hours deliberating over two days in a windowless room in the federal court building in Greensboro.

It’s possible Tuesday will be another long day for the group of 12.

It’s hard to tell what Edwards may be thinking as he comes and goes every day, waiting for jurors to reach a verdict.

The group asked for seven more pieces of evidence Monday, bringing the total number of exhibits requested to 20. Among them are checks, letters, a deposit slip, a transcript and even a voicemail recording.

Since three of the jurors have a financial background, one is a school teacher and the group has requested magic markers, legal analyst Kieran Shanahan thinks jurors are patiently mapping out the case for themselves.

“This jury is taking its responsibility seriously and they don’t care what the time is outside. They’re on their own time schedules inside and they’re going to do the deliberative role they’ve been charged,” she said.

Shanahan called it a complicated case, but others have called the six charges straightforward.

Even if jurors think Edwards used campaign money to hide his pregnant mistress from the public, they have to find that the crimes were committed in the middle district of North Carolina.

Edwards’ campaign office was in the district, but the paper trail leads jurors all over the U.S.

While no one knows exactly what the eight men and four women are working on behind closed doors, it does appear they are painstakingly looking at the exhibits.

Outside that room, Edwards -- and the world -- waits to see if the former presidential candidate will serve any prison time. If he’s convicted, he could face up to 30 years behind bars.

Prosecutors have accused the Democrat of masterminding a scheme to use nearly $1 million in secret payments from two donors to help hide his pregnant mistress as he sought the White House in 2008.

Defense attorneys argued Edwards had little direct knowledge of the cover up, which they say was directed by his campaign finance chairman and a trusted aide who falsely claimed paternity of his boss' baby.

Jurors are due back at 9:30 a.m. Tuesday.
