I have to agree with you. I may not have researched as much as some here but everything I read points to her baby daddy as Webb.My guess is also that somewhere along the line someone has the DNA on her.
then there is all kinds of stuff like this:

Clintons real father is Webster Hubbell, the former Mayor of Little Rock, Arkansas. Hubbell was a law partner at Rose Law Firm with Hillary, and became one of the most important Clinton-insiders.
Then-Governor Clinton appointed Hubbell as Chief Justice of the Arkansas State Supreme Court, but 10 years later he resigned before pleading guilty to federal mail fraud and tax evasion for overbilling clients. Hubbell served 15 months in prison.
The New Yorker reported on rumors that Hillary Clintons affair was first noticed in 1984 at the Governors Mansion during Bills second term, but had started long before.
Apparently, Bill Clinton is infertile. This raises serious character questions about Hillary Clinton If she was elected, this type of sex scandal could open her up to blackmail.
Robert Morrow claimed:
His exact words were, I shoot blanks. Stunned by what Id just heard, I asked him, Then what about Chelsea? And he said, Oh, Webb (Hubbell) sired her.
As the National Enquirer reported (the same tabloid which broke the John Edwards sex scandal), the accusation was being made by former Clinton aide Larry Nichols.
According to well-respected author Edward Kleins (2005) book, The Truth about Hillary, Bill discovered his wife was pregnant by reading it in the Arkansas Gazette.
Its unfortunate, sad really, that Chelsea has no real relationship with Hubbell who I believe to be her real biological father when hes alive and kicking and living in North Carolina.
But it could be shes in denial, despite overwhelming proof that Webb is her real dad.
Whatever Chelsea does or doesnt know about her paternity, Im sure she considers Bill her real dad despite there being no blood ties, Nichols said. I saw firsthand what a doting, loving father he was to his little girl.
He always treated her as if she was his own which in his heart, I believe shes always been from day one.
