Your most conservative candidate to replace LaTourette has to be state representative Ron Young from Lake County. It is possible that they may find him too conservative and go with someone else. It’s a very long list.
I see that Ron Young is from the more rural eastern part of Lake County, but presumably is well known in the suburban (and very marginal, if not Dem-leaning) NW corner of the county adjoining Cleveland. Lake County is still the heart of that CD, and from what I read Young has a history of winning tough races (and beat a Dem incumbent in 2010), so given that he’s also a solid (and proven) conservative I think he could be someone who “hits the sweet spot” for us.
