Divided Government

Preference for Divided Government?

The most important political change of the past half century is the Democrats' and Republicans' transformation from loose ideological coalitions to sharply distinct parties of the left and right. In Washington, the parties are now too far apart ideologically for either to count on winning support from the other side.However, the country's biggest problems are too large for one party to handle, at least in any consistent way. The Democrats did pass health reform on a party-line basis, a remarkable accomplishment, but they did it by the skin of their teeth and with a Senate supermajority which has evaporated. That is not a trick they can keep performing.Under those conditions, the only way to achieve sustainable bipartisanship

is to divide control of the government, forcing the parties to negotiate in order to get anything done. That pulls policy toward the center, which encourages reasonableness. And the very fact that both parties sign off on any given policy makes the public perceive that policy as more reasonable, which makes it less controversial and more sustainable. I think a bipartisan health-care reform would have been only, say, 30 percent different from the one the Democrats passed, but it would have been 50 percent better (many of the Republicans' ideas were good) and 200 percent more popular, which would have made it 80 percent more likely to succeed. (All figures are approximate.)
