BBC online's Nick Assinder has become the latest pundit to question whether Ming Campbell - 65 today - is up to the job of Lib Dem leader.
"Some have started re-examining the way former leader Charles Kennedy was ousted. Mr Kennedy, remember, took the Lib Dems to historic electoral heights only last year, and appeared to have a rapport with ordinary voters," he writes.
"The question that some are asking is whether the fact that there has been a successful Lib Dem leadership coup once this Parliament means there is more, or less, appetite for more leadership turmoil before the next election."
I think I know the answer to the last question....
