After just three weeks on the campaign trail, CaringBridge founder Sona Mehring told supporters Wednesday she will not challenge Rep. John Kline, R-Minn., after all.

“My campaign received tremendous support and words of encouragement,” Mehring wrote. “The level of enthusiasm and people’s confidence in me was humbling. However, I realize my true passion still was with CaringBridge.”

Her departure clears the way for former state Rep. Mike Obermueller, who plans to challenge Kline a second time in Minnesota’s 2nd District. Democrats have indicated they plan to target this district in 2014.

Although Mehring’s campaign was brief, the timing of her announcement is notable for another reason. On Friday, Kline announced he would not run for Senate or governor in 2014. Instead, he will seek re-election to the House.
