If you're oh-so-starved for more analysis, firedoglake has got some excellent analysis - final point being that:

There is no wobble in the indictments handed down today. It's pretty clear. Libby can deal or swing.

Which brings us to David Radler. Who is David Radler? David Radler was the #2 man at Hollinger International. The day after he was indicted by the US Attorney for the State of Illinois Patrick J. Fitzgerald for looting money from the stockholders of Hollinger, he announced he'd rather "cooperate with investigators" (read: rat out his boss, Conrad Black) than spend the rest of his life perfecting the ultimate starch job in the prison laundry. Radler decided he would take Door #2 and do twenty-nine unpleasant months and pay a fine when the prospect of life in prison became a reality.

That's just the way Patrick Fitzgerald works. If the Hollinger case, and the Ryan case, and the Daley Case, and the Al Quaeda case and the Gambino case are any indication, Fitzgerald will now use what he's got to get more.

So it seems possible that Fitz is using this indictment of Libby as a pressure point to get him to leak out more info on Rove's involvement (or potentially even higher?). Interesting...
