Yet as Republicans toast their triumph, they should be careful not to over-interpret it. Their campaign did not offer voters much of a positive agenda; rather, it consisted largely of urging them to blame Mr Obama for all the trouble in the world. That was enough to secure victory, but does not give them a mandate to pursue a wishlist of conservative policies. Although more Americans than ever hold partisan views, a larger number are weary of gridlock and would prefer their representatives to compromise to get things done. For the voters to be satisfied, America will need to find new ways to run its politics.
