CHICAGO – That historically all-white club known as the U.S. Senate is likely to lose what little diversity it has after November’s elections.

Two white men will be competing for President Barack Obama’s former seat in Illinois, now held by Roland Burris, the chamber’s lone African-American. Appointed by the scandal-tainted former governor, Burris won’t be seeking a full term.

In contests in Florida, Texas and North Carolina, black candidates face daunting challenges to joining the august body, from difficulty raising cash to lack of name recognition to formidable rivals.

Blacks comprise 12.2 percent of the nation’s population, but you wouldn’t know it in the 100-member Senate. Come next year, the total number could add up to zero.

“It certainly is not a desirable state of affairs,” said David Bositis, a senior political analyst with the Joint Center for Political and Economic Studies.
