In it, but not of it. TPM DC
The Las Vegas Review-Journal reported in April 1999 that the state assembly, of which Angle was a member, voted 26-16 for a bill that required fluoridation in two counties including the cities of Reno and Las Vegas. Angle was a strong opponent of the measure. The paper reported (via Nexis):
Before the vote, Assemblywoman Sharron Angle, R-Reno, sought to postpone the vote so she could add an amendment to block fluoridation in Washoe County. The Washoe County Commission in 1992 rejected fluoridation, and Angle said the Legislature should not approve fluoridation in her county without a vote of its people.
While another member of the Assembly suggested opponents of the measure were worried about the financial implications of fluoridation, the Review-Journal reported: "Angle said she simply does not like fluoride." Angle added she believed most fluoride used in water supplies could contain "lead, arsenic, [or] mercury."
Here's what the federal Centers for Disease Control and Prevention has to say on the matter:
"For 65 years, community water fluoridation has been a safe and healthy way to effectively prevent tooth decay. CDC has recognized water fluoridation as one of 10 great public health achievements of the 20th century."
