The political retirement of Evan Bayh, at age 54, is being portrayed by various sages as a result of too much partisanship, or the Senate's dysfunction, or even the systemic breakdown of American governance. Most of this is rationalization. The real story, of which Mr. Bayh's frustration is merely the latest sign, is the failure once again of liberal governance.
For the fourth time since the 1960s, American voters in 2008 gave Democrats overwhelming control of both Congress and the White House. Republicans haven't had such large majorities since the 1920s. Yet once again, Democratic leaders have tried to govern the country from the left, only to find that their policies have hit a wall of practical and popular resistance.
Democrats failed in the latter half of the 1960s, as the twin burdens of the Great Society and Vietnam ended the Kennedy boom and split their party. They failed again after Watergate, as Congress dragged Jimmy Carter to the left and liberals had no answer for stagflation. They failed a third time in the first two Bill Clinton years, as tax increases and HillaryCare led to the Gingrich Congress before Mr. Clinton salvaged his Presidency by tacking to the center.A little history lesson.
