Step one: DCCC raises money as usual, only even more effectively with a winner's smile
Step two: Instead of pumping $3.2 million into a vanity contest in the fiercely expensive IL-06, just because it's next door to Rahm's home district, take that same money, $3.2 million, and divide it into 32 $100,000 chunks
Step three:
after the fugn' primaries pump $100,000 each into
thirty-two districts like NY-23, NE-03, or IN-06, where media costs are low. Give the money early, right after the primary.
Step four: win them all.
Add netroots wins and additional seats to taste. Garnish and serve.
In 2010 and 2012: rinse, lather, and repeat.
