NORWALK - Two candidates vying for Connecticut's open U.S. Senate seat are preparing for their second debate tomorrow.

The Senatorial debate comes on the same day as the national vice presidential debate, and unfortunately, some residents in southwestern Connecticut won't be able to tune in to watch.

Officials say the reason behind it has to do with federal regulations as well as an ongoing contract dispute.

The debate is being held at UCONN in Storrs and is being aired by Fox Connecticut, which currently isn't being carried on the Cablevision system.

However, the evening's debate between Republican Linda McMahon and Democrat Rep. Chris Murphy will be streamed live on Fox Connecticut's website.
