I don't think we can or should fight explicitly against poverty--people have to help themselves--but we can and should fight against lack of opportunity. There's a lot less opportunity these days than 25 years ago. It's harder for the poor, even if they want to, to get out of their hole. Thanks to low taxes, our education system really sucks.
It would be nice to see Republicans recognize that it isn't a good thing that the rich are getting richer and the poor getting poorer. I'm always amazed at how many non-rich people vote Republican because they buy into their hype.
