And then there is this story that popped up this weekend:

Rep. Sheila Jackson Lee Booed by Pro-Obama Constituents

Here's the description provided by the YouTube video-maker:

    U.S. Congresswoman Sheila Jackson Lee from Texas (D-Houston) gets booed at Texas Senate District 13 Democratic Convention on March 29, 2008. Though her congressional district is overwhelmingly in support of Senator Barack Obama for President, Congresswoman Jackson Lee is a superdelegate and supporter of Senator Hillary Clinton in the 2008 U.S. Presidential Race. When she took the stage, she had to wait a couple of minutes for the booing and Obama cheering to subside and kept remarking, "I'll wait for you to stop."

From KVUE, the Austin, Texas television station that has more raw video of the booing:

    HOUSTON — On the campus of Texas Southern University was a Democratic Senate District convention unlike the others being held across the state.

    Democrats together, but yet still divided over who should be the Democratic presidential nominee.

    And never more was that more apparent than when longtime Houston Congresswoman Sheila Jackson Lee took the stage.

    A majority of the crowd showed its support for Barack Obama by shouting his name and booing the congresswoman, letting her know what they thought of her allegiance to Hillary Clinton.

    To some, especially Clinton supporters at the convention, the booing came out of nowhere.
