There was earlier speculation that Tryagain is Miles Jackson, a former reporter in the employ of Lou Magazzu. It would make sense. Lou probably does not sit at the computer to type responses to the postings here (although we hear he is obsessed with this site). But he would certainly hire someone with marching orders to attack everyone who opposes him. Here is the skinny on Miles from an informant:
Miles used to work for the Daily Journal. He used to hate Lou and really went after him in a big way. Lou complained and complained and screamed at the Daily Journal. So, the Daily Journal did what I thought was unheard of, they took him off the County news. Newspapers are not supposed to do that. When I questioned them about it they said they felt Miles was going overboard, or was obsessed about Lou. Then, last year Miles appeared at the Democratic headquarters while the vote count was coming in. It seemed strange to me that he was there. Then we found out he had been hired by Lou to write for the Democratic party. Even more strange.
