The Roseville Republican, who is wrapping up his second term in the Assembly, pledged to continue to oppose tax increases if elected to the Senate.
"Since my election to the Assembly in 2006, I have worked hard to bring common sense conservative principles to the State Capitol," he said. "I will not support any tax increase on the people or businesses of California and I will never compromise my principles just to 'get a deal done' or move the process along."
Gaines is seeking to replace GOP Sen. Dave Cox, who died last month at age 72. Assemblyman Roger Niello, R-Fair Oaks, is also expected to run for the seat.
A special primary election will be held with the Nov. 2 general election. If no candidate wins more than 50 percent of the vote, the top vote-getter from each party will compete in a runoff on Jan. 4.
The 1st Senate District encompasses 12 counties, including Amador, El Dorado and parts of Nevada, Placer and Sacramento counties. Gaines' press release states that about 34 percent of the district's likely voters live in the 4th Assembly District, which he currently represents.
