Bernie doesn’t have a real chance of overtaking Hillary! anyway. So it really is an exercise in futility.
On the Dem side, there are 8 more primaries/conventions left.
I don’t think he’ll be spending on DC, PR or the USVI.
The RATS are already done in WA.
All that’s left are the June 7 primaries in CA, MT, ND, NJ, NM and SD. Four of those states are relatively inexpensive to advertise in (MT, ND, NM, SD). That leaves CA and NJ, which will be expensive. Not sure if much more Bern! needs to be felt anyway at this point in time.
Bern the money...I like the smell of Bernt money in the morning.
