On Feb 20th a complaint was filed by Thomas Cook from Bloomingtong, IN.  The complaint is filed stating John McCain did not get the required 500 signatures from the 4th congressional district.  You can view a copy of the complaint here.   According to Thomas Cook’s article the Democratic National committee’s response to his challenge was:

“Despite the fact that the McCain campaign clearly failed to qualify for the ballot, Republican Attorney General Steve Carter and Republican Secretary of State Todd Rokita (who recently endorsed McCain) rubberstamped it anyway, trying to sneak McCain onto the ballot. Clearly, the Republican Culture of Corruption is alive and well within the McCain campaign”

I’ll continue to do some reasearch on this topic and make further posts as I gather some more information
