Again Jonathan Rauch pens a thought-provoking piece.
If you don’t want to read it (though why wouldn’t you? Rauch is pure pleasure to read) his thesis is this. The Republican and Democratic parties have changed since the 1960s from broad coalitions embracing a number of different ideologies into distinct groups who have very little in common ideologically. The result is that the ideological center of each party is far removed from the ideological center of the country. Under one-party government, the president has to lead from the center of his party, which alienates about two thirds of the country. The opposition party has very little to gain by compromising, since the credit for the result, if positive, will go to the party that dominates government. When the minority party dominates at least one branch of government, there is a greater incentive for compromise. Rauch argues that Reagan, Clinton and Bush II (from 2001 to 2002) all fared best with divided government, and thinks that Obama’s ability to govern from the center of the country and forge forward will be improved if the Republicans take back at least one house this November.
I have some trouble with Rauch’s attribution of Bush’s collapse in popularity to the one-party government that came on in 2003. The Republicans did pass another tax cut that year, and they did manage to stay the course in Iraq, and Bush did beat Kerry with a clear, if narrow, majority. I would say that Hurricane Katrina, and the perception of incompetence and cronyism in the response to it, was what did for Bush’s popularity, not one-party Republican government. But in every other way, Rauch’s description of the dynamics of one-party government versus divided government looks spot on.
As to Rauch saying that the country will be more governable and Obama more successful if the Republicans take back one or both houses in November, my answer is “yes, IF.” Right now, the Republicans are dominated by their most extreme elements, which was their predictable response to the defeat of John McCain, who was seen as one of the Republicans’ most moderate leaders. If 2010 brings in a crop of Palinite Republicans, it won’t do a thing for Obama or the country. The GOP will (rightly) say that its hard-line, no-compromise strategy has been a brilliant electoral success, and will go right on doing the same thing in the hope that it will bring them the White House in 2012. On the other hand, in 2006 it was not extreme Democrats who profited most from the anti-Republican backlash, but the more moderate “Blue Dog” Democrats. If the same thing happens in November with the Republicans, with a crop of moderates giving the GOP its new majority in at least one house, then I could see a reasonable chance for deals to be struck on health care, deficit reduction, environmental policy, and our other major problems.
