The Fresno Democrat said in a statement that while the opportunity to run in the 16th Senate District is "appealing," he wants to serve out his most recent term in the Assembly and honor a commitment he made to his wife and family to "create a balance between my home life and work."
"We are anxiously awaiting the arrival of our second child in July, and I want to uphold my commitment to my family and the 31st Assembly District," he said.
Rubio, a freshman Democrat from Shafter, resigned his 16th Senate District seat last week to take a job heading California governmental affairs for Chevron Corp.
Gov. Jerry Brown has not yet set a special election date, but there is no shortage of candidates interested in seeking the seat.
