I think it’s not unusual for a guy to be quite effective at one (lower level) but not so good at a higher level. A good example was Ambrose Burnside, considered a pretty good corps commander, but a terrible commander of the army.
Lewandowski was just fine at the state level, one at a time. It’s now time for Manafort to bring it home.
Think of Corey as the starter, and Manafort as Mariano Rivera.
I keep thinking of what Manafort said about the polling on Trump’s support among Mexicans. It was so simple it blew my mind. They simply polled more Mexicans in NY and CA.
The same could be said for the latest national polls. What’s stopping them from polling more people in states that Clinton beat Sanders handily. It’s that easy.
