Not only does the new Washington Post-ABC News poll have bad news for President Obama on the economy, one edge he held over Mitt Romney appears to be disappearing:

One advantage that Obama held in previous polls — a big lead on enthusiasm — is no longer evident. In the new poll, 48 percent of Obama’s backers say they are “very enthusiastic” about his candidacy, compared with 42 percent of Romney backers who feel that way about the Republican’s campaign — a difference that is not statistically significant. Obama had a 13-point edge in July in this measure; his lead was 25 points in May.
