What's a burn rate? It kinda means the amount of dough a candidate blows through to keep their operations up and running. A candidate with a low burn rate raises good money and spends very little of it. A candidate with a high burn rate is spending like a drunken sailor.
Much had been made of Christine's 'high' burn rate earlier (as a sign of a weak campaign) by some prominent Illinois political blogs, so this is why I'm pointing it out.
The most telling figure is this one:
Itemized Contributions from District:
Duckworth: $4,350 from 8 residents
Cegelis: $25,704 from 85 residents
That pretty much says it all.
