EJ Dionne: It's our system on the cliff

The United States faces a crisis in our political system because the Republican Party, particularly in the House of Representatives, is no longer a normal, governing party. . . . .
In a democratic system with separated powers, two houses of Congress, split between the parties, a normal party accepts that compromise is the only way to legislate. A normal party takes into account election results. A normal party recognizes when the other side has made real concessions. A normal party takes responsibility. By all of these measures, the Republican majority that Speaker John Boehner purports to lead is abnormal. That is the meaning of his catastrophic failure to gather the votes for his “Plan B” proposal on the “fiscal cliff.” Many of his most radical members believe they have a right to use any means at their disposal to impose their views on the country, even if they are only a minority in Congress.
. . .
In the longer run, the non-tea party wing of the GOP will have to decide whether it wants to be subject to the whims of colleagues to their right or look to the center for alliances with the Democrats. The choice is plain: We can spend two years doing absolutely nothing, or we can try to solve the country’s problems. This includes the problem of gun violence, and the question is whether the GOP will reject the tone-deaf extremism of NRA chief Wayne LaPierre’s bizarre response to the killings in Newtown, Conn.

Our political structure has been disfigured in another way: In November’s election, Democrats failed to win the House even though they received about a million more votes in House contests than the Republicans did. Republicans were protected by gerrymandered districts and by political geography: Democrats tend to win urban and certain suburban districts by overwhelming margins.
In Pennsylvania, to pick a stark case, Democrats edged out the Republicans in the popular vote for House races. But given how the districts were drawn, this resulted in the Republicans winning 13 seats to only five for the Democrats. Both parties gerrymander, of course, but Republicans had far more influence over the process this time because the 2010 election gave them dominance of so many legislatures. Thus did one election shape our politics for a decade, even though the country changed its mind one election later.. . .
