I want to spend $100 on August 15 and I need your help!

Like many working stiffs, I get paid on the 15th and the 30th.  This site has made me more active in donating to Democrats across the country, and in the past, I've made recurring donations to Paul Hackett, Ned Lamont and John Kerry.   Lamont actually won!  I am so energized by that victory that I want to redouble and expand my efforts.

Here's the deal: I'm a Catholic school teacher with a limited income, so I am working with a fixed budget.  I can only afford about $100 per paycheck to contribute, and that's already going to stretch me thin. I wish I could open up a checkbook and give the max to every House and Senate candidate in the country, but it's not gonna happen.

I'm counting on the educated and informed members here to give me advice on who to donate to and why.   Should I split the $100 ten ways, or give it all to one candidate?  I have a strong inclination to send some dollars Webb's way, but after that, I'm pulled in many directions.  Please help!
