The consensus on Barack Obama's acceptance speech Thursday night, and in effect on the Democratic National Convention as a whole, is that it was a bust.

One reason may be optics. Obama was scheduled to deliver the speech in a stadium seating 64,000 people. But on Wednesday, after Charlotte, N.C., had been pummeled by periodic rainstorms all week, organizers moved the event to the convention hall.

The last two stadium acceptance speeches, in 2008 and 1960, were delivered in Denver and Los Angeles, where it seldom rains in the summer. That's not true of Charlotte -- or of Tampa, Fla., where Republicans took a risk by scheduling their convention at the start of hurricane season.

So Obama spoke at the same podium as Bill Clinton had the night before. The comparison was not flattering to the 44th president.

Clinton was animated, loose, constantly ad-libbing, varying his gestures and expression. Obama seemed more mechanical, less fluent. The contrast with the videos shown earlier of his campaigning in 2008 was not helpful.

And, perhaps unexpectedly, John Kerry and Joe Biden delivered more interesting speeches before Obama spoke.

Kerry effectively exploited Mitt Romney's inexperience in foreign policy and his omission of a tribute to the troops during the GOP convention. Biden painted a picture of Obama decisively making difficult decisions 30 paces from his own office.

The major problem with Obama's speech, however, was content: It was the same old same old. Just as he didn't pivot on policy after his party's thumping in the 2010 elections, so he didn't pivot from his accomplishments in his first term to what different things he hoped to accomplish in a second.

He said he would pursue certain "goals" in a second term. But the goals were vague -- invest in the economy with the money we're no longer spending on war -- and in many cases rehashes of things he has said before. And there was not even the vaguest description of how specific policies might achieve these goals.

In his peroration, Obama made appeals to different core Democratic constituencies, like those made repeatedly by other speakers in Charlotte, sometimes even after 10 o'clock Eastern time, when the broadcast networks began their coverage.

The delegates roared again and again at endorsements of access to contraceptives (actually, free contraceptives), same-sex marriage and nondeportation of young illegal immigrants who meet certain conditions. Requiring picture identification at the polls was described as similar to beating up blacks trying to vote 50 years ago.

Young people, single women, gays and lesbians, blacks and Hispanics came out in large numbers and swelled Obama's majority in 2008. He needs them to turn out heavily again. The Obama brain trust could only hope that these people followed the lengthy proceedings at the 5,000 "watch parties" organized by the Democratic Party or by the constituent groups themselves.

But the evidence from polls, and the fact that the Democrats felt they had to make these appeals, suggests that enthusiasm for Obama, except among African-Americans, is lagging behind 2008's. Did the convention and Obama's speech rekindle the spark of his first presidential campaign? It doesn't seem likely.

The Democratic Party throughout its history has been a coalition of disparate groups that, at their strongest, add up to a majority. But when the party has to rally them with appeals that turn off moderates and independents, it's hard to get to 50 percent.

Especially when you make unforced errors, like writing a platform that didn't mention God -- or Jerusalem as the capital of Israel -- and then having the oversight corrected to resounding boos on the floor.

Polls tell us that the Obama Democrats were at the cusp between victory and defeat after Mitt Romney's selection of Paul Ryan and before the two conventions began.

Polls next week will tell us where the race is now. Pundits are looking for bounces, but polls conducted over weekends, and especially over the holiday weekend that separated the two conventions, are problematic.

Two events after the Democratic convention threaten to undermine any positive bounce.

One is the unemployment numbers released Friday morning. The unemployment rate is down to 8.1 percent but only because the labor force is shrinking. Fifty-somethings are going on disability, and twenty-somethings are living with their parents.

The other is the devastating portrait of Obama in Bob Woodward's latest book. "Presidents work their will -- or should work their will -- on important matters of national business," Woodward writes. "Obama has not."
