Look for Matier and Ross to report on the Chronicle tomorrow (Thursday) that Mark Leno's team has taken a poll on how he would fare in a challenge against Carole Migden  for state Senate in 2008.
The poll, I'm told, was encouraging to the Leno camp. The Assemblyman will make up his mind in January, but I'm getting the strong sense that this is going to be a go.
And what a political free-for-all it will be.
