Timken's ousting of Borges w/in the OH GOP could well mean the Republican primary goes uncontested.
Maybe, but it'll also probably mean a weaker Republican ticket and certainly will mean a weaker state party. At the least, there'll be a contested gubernatorial primary.
I don't think Timken means a weaker party at all. She's a bundler with big money connections. She'll increase party funding by herself. considering that many republicans felt that trump (and his coat tails) won Ohio inspite of Borges I don't think they will see much drop. The bench is deep in Ohio for republicans, they'll have a lot of money, I don't think Timken weakens the party at all.
