He was defeated by Democrat Pam Iovino.

In a press release, Raja said: “Leading the Republican Party in Allegheny County and working with our entire RCAC team including all local chairs and committee members has been an honor and privilege. I’ve offered a vision of servant leadership to build our party and put our Republican Party principles into action. Despite a challenging environment, I believe our efforts and positive results will speak for themselves. I thought it was important to wait until after the May 21 Primary to make this announcement. I’m so grateful to my wife, Neeta, and our daughters for being so supportive of my public service.”
