Add one more big endorsement for David Garcia, Democratic candidate for Superintendent of Public Instruction: The Arizona Chamber of Commerce & Industry. That's on top of the endorsements Garcia received from three former Ed Supes: two Republican, one Democrat.

I called the earlier endorsements possible game changers, since under most circumstances, Republican superintendents could be expected to support the Republican candidate. This new endorsement of a Democrat for state office by the Chamber of Commerce is equally, if not more, significant.

Here's the Team Garcia press release:

The Arizona Chamber of Commerce and Industry announced its endorsement of Dr. David Garcia for Superintendent of Public Instruction today.

“We are excited to endorse a candidate who shares our mission of advancing Arizona’s competitive position in the global economy by advocating for a world-class education system and policies that stimulate economic growth and prosperity for all Arizonans,” stated President and CEO Glenn Hamer.

Voicing his appreciation for the endorsement, Dr. Garcia stated, “I firmly believe Arizona is capable of having the most innovative education system in the country. We are small, flexible and fearless, and if we recognize and utilize our strengths, we can and will provide all of our students with a world-class education.

I look forward to partnering with our business and education leaders to put Arizona in a position to lead both nationally and internationally.”

Dr. Garcia is an Arizona native, U.S. Army veteran and product of Mesa Public Schools. The former Associate Superintendent of Public Instruction for Standards and Accountability, Garcia is widely regarded as a national expert on education policy and research. He currently teaches future education leaders at Arizona State University and has two daughters in public schools.
