Are we heading for an early general election?

I alluded to the possibility yesterday on the premise that with Brown being seen as the saviour of the financial markets going to the country before the effects of the meltdown are devastating the country.

Niall Patterson over at Boulton and Co seems to think that the runes are in the air so to speak

let's assume Glenrothes is held (my bet is that without that result, which would itself overturn the current conventional Westminster wisdom, Labour would worry about holding any of their Scottish heartland, a necessity for a fourth term).
Given that, could Mr Brown call an election early in 2009, framed around the economy?

However the window could well be shortening by the day.Today's unemployment figures which have seen the fastest rise in those out of work since the dark days of John Major allied with new fears of recession which has sent the markets into a spin show that the room for manoeuvre is narrowing rapidly.
