Yup. From 2016:
“This election cycle, 393 of 435 House representatives, 29 of 34 senators, and five of 12 governors sought reelection (several of the governors were prohibited from seeking another term). Of those, 380 of 393 House members (97%), 27 of 29 senators (93%), and four of five governors (80%) won another term. These members of Congress and governors not only won renomination, but also won in November.”
