A legislator now spends roughly anywhere from 20-50 percent of her or his time fund-raising, either to pay for their last campaign or to build a war chest for their NEXT campaign. With that kind of emphasis on money, it is easy to see why money in politics has become such a big issue in both Republican and Democrat circles! The joint issues of "Corporations are Not People" and "Money is Not Speech" are among the very few that unite most Republicans and Democrats across the United States, at least according to my friends in Move to Amend!
