He did that, indeed.
When he ran for state senate he knocked the entrenched RAT out, it’s a long story but is in “Obama Nation” and “The Case Against Barack Obama.” Incumbent thought she’d run for Congress, then changed her mind, and obammy managed to “prove” she didn’t have enough signatures on her candidacy petition.
Then when he ran for US Senate, somehow the sleazy divorce records of the Republican candidate were made public. hmmm...
Make that “enough VALID signatures”
