The chart from Washington Post shows that if you add up money spent by candidates and support groups, Walker outspent Barrett 2-1 rather than 7-1
Walker spent 29.3 Million. His support groups spent 16.3 Million
Total: 45.6 Million
Barrett spent 2.9 Million. His support groups spent 17.9 Million.
Total: 20.8 Million
It's in the range of 2:1 rather than 7:1.
A lot of diaries in the past couple of days seem to conclude that all hope is lost because we were outspent 10:1 and this will continue. I don't think that it's true. In general democrats receive as much money as the republicans. I don't think we are going to lose any election just because of money.
Also, one more question - why did Barrett not spend nearly 25% of the money he collected - i.e. left it unspent?
