Wendy Davis, the Democratic candidate for Texas governor, has replaced her campaign manager, yet another sign her campaign may be on the rocks.

Karin Johanson, who joined Team Wendy in October and who managed the campaign of Sen. Tammy Baldwin, D-Wis., will be replaced by state Rep. Chris Turner.

“After building one of the most competitive campaign organizations Texas has seen in decades, Karin Johanson has let me know that she believes it’s time to hand off the reins of the campaign management for our final push toward election day,” Davis said.

Johanson had three decades of experience in Democratic politics. Turner does not have as much campaign experience.

It is unclear what prompted the change, but Johanson says she suggested Turner be her replacement.

"I am proud of what we have all built in this campaign," Johanson said. She added that she is "going to go home and spend some time this summer with my 90-year-old father and lose the pounds I gained from eating tacos for breakfast, lunch and dinner."

Even MSNBC showed pessimism toward Davis' campaign, calling the shakeup a “last-ditch effort to turn her campaign around.”

After a slew of bad headlines in late April, the Davis campaign's spokesman resigned. Bo Delp, originally Davis' communications director before being demoted to deputy, resigned with a similar statement.

“I am proud of the work I have done, and know that my successor will continue to build on my successes, and my mistakes, to do what is necessary to win in November,” Delp said in his resignation letter.

Davis is currently polling 12 points behind her Republican opponent, state Attorney General Greg Abbott.
