That would not be good news. No candidate until 60 days out? Say hello to 2nd term Obama.
I look at it the other way...if we had a nominee now, Obama would be hammering on him day in, day out, until November.
This way, if he doesn't know who to focus on until June (or August), he's got that much less time to dump on the GOP nominee, whereas the GOP nominees can and should start to be focusing on the last four years under the SCOAMF.
