United States President Barack Obama won his 34th and 35th consecutive Democratic primary contests on Tuesday night, claiming victories in Arkansas and Kentucky.
But his margin was surprisingly small in Arkansas - a state in which he was opposed by Tennessee lawyer John Wolfe, who had previously been on the presidential primary ballot in Louisiana, Missouri and New Hampshire and will be on the ballot in Texas next week. Wolfe has also run unsuccessfully for Congress four times.
With 61% of precincts reporting in Arkansas, Obama took 60% to 40% for Wolfe. In Kentucky, with nearly all precincts reporting, 42.1% of Democratic primary voters opted for "uncommitted" rather than backing the president, who received 57.9%.
Those results come two weeks to the day after Keith Judd, a convicted felon incarcerated in Texas, won 41% of the vote against Obama in the West Virginia primary.
Although the results haven't stopped Obama's march to renomination - he officially clinched the Democratic nod on April 3 - they remain an indicator of not-insignificant pockets of unrest within his party.
Political observers say race may be less of a problem for Obama than the broader cultural disconnect that many voters in this region feel with the Democratic Party.
