Clinton won't be remembered as a great president, because he wasn't one. History has a way of sorting these things out quite nicely. He will be remembered for a blue dress, a cigar, a slightly plump White House intern and a lie to a television camera. He knows this and has just begun to kick against the goads.
Accomplishments? Outside of high jacking the welfare reform law from the Pubs what else was there?
He was fortunate enough to surf on the dot.com wave. That;s it.
Deep down he knows this and it's tearing him apart.
Clinton will get the LBJ treatment: a talented but crooked, favors-for-cash pol. Whitewater will not go away, and it will lead historians back to the rest of the Arkansas mess. The sale of strategic technology for campaign cash will not go away. The shredding of the campaign finance laws will not go away. The relentless attacks, including IRS harassment, on critics will loom ever larger. Historicans will ultimately realize that the critics and investigators were right. Clinton's primary achievement in office was survival, and he did it by systematic obstruction of justice.
LBJ, though personally corrupt, will always get credit for his leadership on the Civil Rights and Voting Rights Acts and for Medicare/Medicaid. A lot of other things -- Vietnam, the hijacking of the Civil Rights movement by hucksters, the overreaching of the Great Society -- went wrong, but LBJ did have larger purposes, on race especially.
But there is nothing similarly redeeming in Clinton's record of accomplishment. He had the luck to be president during good times which he had precious little to do with (end of the Cold War, spending the peace dividend, the internet boom). The Clintonoids are already reduced to trying to take credit for balancing the budget and welfare reform, which were driven by the Gingrich-Armey era Republicans and which Clinton actually opposed. Bottom line: a personally corrupt, albeit clever, little man who wasted a remarkable opportunity.
Historians are as salacious as anyone so the sexcapades will not be forgotten, but the systematic corruption will be the story.
