What did Judge Grendel Mean? Who was he talking about?

About a year ago then State Sen. Grendel said the following when discussing who could replace him when thought about leaving taking the House Seat he won while serving as the OH-18 State Senator:

"I have a duty to make sure that whoever fills the other seat shares the principles and values of the constituents who elected me to that seat," he said.

"The second seat needs to have a real fiscally conservative, family-values Republican who has a record that matches those qualifications."
