Walter Reddy of Weston, a former artist and ornamental-plaster contractor, has announced he will challenge incumbent state Sen. Toni Boucher of Wilton for the Republican nomination in the 26th District.

An apparent political newcomer, Reddy is calling for repeal of a state gun-control law enacted in the wake of the December 2012 Newtown school shootings that left 26 people dead.

Boucher voted for the legislation, which had wide bipartisan support and was signed into law in April 2013.

The 26th Senate District includes Westport and six other towns.

In a prepared statement, Reddy said the law was approved "based solely on raw emotion -- not facts or data." He opposes the law, he said, because it was enacted without investigative reports of the Newtown shootings, it unfairly punishes gun owners and imposes on taxpayers the high costs of mental-health services.

The law includes sweeping restrictions on assault weapons and large-capacity ammunition magazines. It passed 26-10 in the Senate and 105-44 in the House of Representatives.

Asked in an email what his three priorities would be if elected, Reddy listed only repeal of the gun-control law.

He did not respond when asked if he had held any public offices, but he lists none on a resume he issued. He also did not provide his age when asked.

Reddy is a 1971 graduate of Wilton High School, according to the resume. He attended Norwalk Community College in 1972 and the Silvermine Art School from 1972 to 1975.

He now operates Pure Gold Grains LLC, a company he founded last year that is seeking a U.S. patent on a new "monetary unit" of pure gold and silver, the resume states.

Since 1975, he has worked as a portrait painter; a painting and restoration contractor; done custom-plaster finishes and silver-leaf and gold-leaf decor; and worked for short periods in several ventures related to paying for services with gold and silver, according to the resume.

Boucher, 64, is seeking a third term in the Senate after briefly considering a run for this year's GOP gubernatorial nomination. She is the upper chamber's deputy minority leader and served six terms as a state representative before her election to the Senate.

Reddy was sharply critical of her in his prepared statement, saying Boucher "voted in lock-step" with Gov. Dannel Malloy and the Democratic leadership on the gun-control bill without facts to support the measure.

The bill also was supported by the Republican legislative leadership, which joined Malloy in celebrating its signing.
