What Wulfric said.
I don't really feel confident about Strickland, he doesn't seem to be a good fundraiser and his Gov record seems to be a net negative for him. The Rs will play ads over and over of him of the job losses when he was Gov which was inevitable. I still feel Tim Ryan would've been a better bet here.
Strickland's not the fundraiser Portman is, but it doesn't matter too much. Democrats always get significantly outspent in Ohio. See: Brown in '12. So long as he can keep pace, he'll be okay. And Warren's done a lot of fundraising for him. Biden's done some, as have other bigwigs. He'll be okay.
Strickland's gubernatorial record was actaually fairly good, in hindsight. Tops in job growth in education toward the end. People are also more understanding now that the entire country was hurting, and it wasn't Strickland who crashed the stock market.
Meanwhile, Portman's entire reputation as a moderate is crashing down around him, and his exp. as Trade Represenative is going to hurt this cycle.
Ryan is holding off on a statewide bid so he can run for Governor in 2018.
