Over at the RCP Blog, Tom Bevan notes Lynn Sweet's scoop on the potential Senate bid of Rep. Jan Schakowsky (D-Ill.), a six-term congresswoman from northern Chicago, and a poll she commissioned to test the waters:

Lynn Sweet of the Chicago Sun-Times has the scoop on Jan Schakowsky ramping up a potential bid for the United States Senate. According to Sweet, Schakowsky commissioned a poll from Celinda Lake (April 19-22, 600 Dem LV, MoE +/-4%) showing her with a slight lead over her two main rivals, State Treasurer Alexi Giannoulias and the anemic incumbent Roland Burris:

Schakowsky 24%
Giannoulias 22%
Burris 18%
Undecided 36%

Schakowsky told Sweet she will make a final decision by June 8.
