Ted Strickland is probably going to end up as the Tommy Thompson of 2016, an over the hill former governor who is running more as a reflection of their state party's horrible bench and will probably lose by somewhere in the mid single digits.
Unlike Thompson, he's running in the good electorate year, not the bad electorate year. (But on the other hand, unlike Thompson, it's not an open seat race so is harder for Strickland.)
Portman is a strong incumbent but with first Kander and now Strickland jumping in, Dems must feel they have a good year coming.
