Washington Mayor Adrian Fenty hinted in an interview Monday that President Obama may have raised the bar with the city's African-American community.

"Maybe in the African-American community, despite the results, despite the effectiveness of the government, they're saying, and again I've heard this door to door, 'Do an even better job connecting, engaging, that's what we have grown to expect from not just mayors but other leaders,' " Fenty told Fox 5 D.C. "And I hear it. I hear them. I understand where I've fallen short."

A Clarus Poll released last week shows D.C. City Council Chairman Vincent Gray leading Fenty 45 to 38 percent among likely Democratic primary voters, with 14 percent undecided.

Fenty and Obama appeared to be on friendly terms during the inauguration festivities in January 2009. But the president did not endorse in the race, and Gray was able to capitalize on a run-in with the president at a Washington Mystics game in August. He had a photo taken of the men shaking hands, which he tweeted to his supporters.

The city's primary vote is Tuesday. The winner of the Democratic primary is expected to go on and clinch the mayor's office in November.
