Deliberations will stretch into a fourth day in John Edwards’ trial and there is no telling if jurors are any closer to deciding whether he used campaign money to hide his mistress.

In all, jurors have deliberated on a verdict for nearly 20 hours.

Edwards and his daughter, Cate, have developed something of a routine, walking together down West Eugene Street to the front of the federal courthouse each morning.

Edwards, so far, has declined to comment on the deliberations and what he is thinking as the jury asks for more evidence and pushes deeper into the week.

So far, jurors have asked to see 22 pieces of evidence.

On Tuesday, the group asked to see two letters. One letter was from wealthy heiress “Bunny” Mellon to her lawyer, and the other was from her lawyer to an Edwards staffer.

What sets aside the two pieces of evidence from others requested before Tuesday is that the letters were written in 2006.

 Until now, jurors seemed to focus on evidence from 2007 and 2008.

While it’s not clear what looking further into Edwards’ past means, or which side that favors, legal analyst Kieran Shanahan believed the jurors will make a decision -- meaning the case will not end with a hung jury.

“Listen, three week trial, three days of deliberation. Let’s don’t push the panic button. Let’s let this jury do its job,” he said.

If convicted, Edwards faces up to 30 years behind bars. However, analysts think that sentence is unlikely.

The jury picks up Wednesday where it left off Tuesday afternoon.
