Technically justice is a part of the executive branch. The separation of powers are between different branches.
Obama supporters were ok with cancelled elections as well. Supporters are always going to want that kind of thing. Doesn't matter what side they fall on.

The three branches are Executve, Legislative and Judicial. The justice department is part of the judicial branch, not the executive branch. Law enforcement is in many ways an extension of the court system. They are officers of the law, and the judicial system establishes and enforces the law.
That article started by saying they supported suspending elections, then changed to saying they would prefer a third Obama term over Hillary or Trump. Those are two very different things. I’d be interested to see the actual question that was polled. The primary difference is Obama would never claimed elections were rigged to attempt to get a third term.
