Obama has been quietly having a hard time in more primaries than almost anyone has realized

Do you see a pattern here?  From Real Clear Politics:

Tuesday night, President Obama continued his streak of poor primary performances in culturally Southern states. He received 58.4 percent of the vote in the Arkansas Democratic primary against token opposition, and 57.9 percent of the vote in the Kentucky primary against no opposition (42.1 percent of the vote went to "uncommitted"). In the latter state's Harlan County, in the heart of coal country, Obama received 26.2 percent of the vote.
This comes on the heels of losing 40.6 percent of the vote in West Virginia to a Texas prison inmate, 21 percent of the vote to “uncommitted” in North Carolina, 24 percent of the vote to token opposition in Louisiana, 19 percent of the vote to “uncommitted” in Alabama, and 43 percent of the vote to various candidates in Oklahoma. . . .
There are only seven sitting presidents who have ever received less than 60 percent of the vote in any primary: Taft in ’12; Coolidge, ’24; Hoover, ’32; LBJ, ’68; Ford '76; Carter, ’80; and Bush ’92. All of these presidents, with the exception of Coolidge, were not re-elected . . . .
