Davis filed at uShip's flagship office in Austin where she was joined by supporters and volunteers.
"I'm running for Governor because I believe all Texans should have a voice in their future and a place in Texas' future," Davis said. "Today is the official start of that journey -- a journey that means so much more than filing paperwork."
Davis says her gubernatorial campaign will focus on job creation and preserving the Texas promise for future generations.
Texas Attorney General Greg Abbott also registered his candidacy on Saturday, as did tea party conservative Lisa Fritsch. They all seek to succeed Republican Gov. Rick Perry, who isn't seeking re-election.
