This isn’t a slam at Jeff, but he misses the key to a Plummer Candidacy. If Plummer puts in $5,000,000 (or just barely more) than Barack can raise $12,000 a person and coordinated party money–money he won’t need.
Any self-funder makes it easier for Barack in many ways.
Taking a small bit from the only decent resource I know of this–the Hotline:
Personal Funds Spending > $1,018,640 (2X threshold) then spending limit jumps to $6,000
Personal Funds Spending > $2,037,280 (4X threshold) then spending limit jumps to $12,000
Personal Funds Spending > $5,093,200 (10x threshold) then spending limit jumps to $12,000 and party committees can spend unlimited coordinated amounts on the campaign
Even Cox boots it up to $6,000/donor.
Just to add to the Republican nightmare the initial threshold is $509,320–though I don’t have the exact figure that donors can increase too at that point.
UPDATE: From a Democratic Source that demonstrates I only sort of get it, the intial threshhold doesn’t increase how much you can raise. It’s when you double the threshhold that increased limits kick in.
IOW, Cox says he’ll put in $1,000,000. That wouldn’t increase the limit. But $18,000 and some change more, Obama collects double.
