Does Fred Thompson Have Staying Power?

So Fred Thompson is going to announce?

I wonder if he's in too late, even though the election is more than a year away.

His spring and summer-long dithering suggests some ambivilance, some indecision: his leaked announcement plan looks anti-climatic and underwhelming to me.

It'll be interesting to see if he shoots up in the polls or gets the politician's dreaded deat-cat bounce.
