Snopes agrees with you, the 34 people listed by them on the following page who were associated with either Bill or Hilary Clinton all died of explainable natural causes, suicides or natural deaths during the 90s, mostly 1992 to 1994:
Please don't drag that tired old conspiracy theory into this. If you start with just 500 people and kill them off at ~0.8%/year (roughly the annual US death rate), at the end of ten years close to 40 of them should be dead, and there are a lot more than 500 people "associated" with the Clintons.
