Capital Tonight on YNN:

Tonawanda attorney Kevin Stocker created a campaign committee today for a run in the 60th Senatorial District, which is currently represented by Republican Sen. Mark Grisanti.

According to the filing, Stocker, a Republican who ran a close race against Democratic Assemblyman Robin Schimminger in 2010, is serving as his own treasurer.

Stocker is a private practice attorney who served as deputy attorney for the Town of Tonawanda from 1993 to 2006. He’s something of a perennial candidate, having run unsuccessfully for various state and local offices on several occasions.

...Stocker has been talking about a challenge to Grisanti since at least early last month, when he told the Tonawanda News that Grisanti, a former Democrat, had failed to keep his word to voters when he crossed the aisle last summer to vote “yes” on same-sex marriage.

Grisanti is already facing one challenger: Former Democratic Erie County Legislature Chairman Chuck Swanick, who has been endorsed by the Erie County Conservative Party and also has the backing of the National Organization for Marriage.
