Consider the contrast between two groups of Democrats, in Wisconsin and in the nation's capital.
Washington Democrats, including President Obama, have allowed conservative Republicans to dominate the budget debate so far. As long as the argument is over who will cut more from federal spending, conservatives win. Voters may think the GOP is going too far, but when it comes to dollar amounts, they know Republicans will always cut more.
In Wisconsin, by contrast, 14 Democrats in the state Senate defined the political argument on their own terms - and they are winning it.
