If Sherrod Brown runs, we loose. If Ryan runs, we loose. If Hackett runs, we still loose.
DeWine is the weakest GOP incumbent senator in the country, sadly there is no candidate of Casey esq stature to challenge him as there is in PA... nominate Brown and yes the Dems would probably lose, Ryan has a fair chance... Hackett I just don't know, if he wanted it he would probably make a good candidate, but could he win?
Its important to remember that Hackett would be facing a veteran republican incumbent in a conservative leaning state, all be it that this republican incumbent is very vulnerable… it also should be considered that running for Senate is a huge leap from running for Congress. IMHO Hackett would either set the race a light or fizzle out… and I fear with so little experience it might well be the later, he made gaffes in the house race (indeed they might have cost him the race), he would probably do the same in a senate race.
At the same time Tim Ryan would be a competive and credible moderate, a safer choice in short but perhaps lacking the charisma of Hackett… but perhaps safely would be preferable to “pizzazz”.
