A new political action committee has formed to fight a proposed overhaul of Clark County government. The group hopes to counter the money and message of another political committee backing the adoption of the home rule charter.The opposition committee, known as Don’t Lose Your Voice, trails the pro-charter political committee in money and, seemingly, prominence — at least for now — but its supporters say it’s working on a ground-up campaign.“We plan to counter with a grass-roots effort,” said Sharon Long, the committee’s treasurer.So far, the PAC, formed in late August, has raised $4,150, according to filings with the Washington state Public Disclosure Commission. The money will be spent primarily on signs and literature, Long said.Most of it has come from one source, Chuck Miller, a Republican activist who’s previously fought against same-sex marriage and illegal immigration. His wife, Anna Miller, is Clark County Commissioner David Madore’s personal assistant.Chuck Miller did not return a phone message Friday.Other donors include Jennifer Sohn, who contributed $500, and Commissioner Tom Mielke, who donated another $500. With less than two months before voters will decide whether to approve the charter, the Don’t Lose Your Voice PAC is part of a coordinated effort by Clark County Republicans to fight it. Last month, local Republican precinct committee officers voted to support a resolution opposing the proposed charter, approved in spring by a 15-member board of freeholders.Charter opponents also have created a website, www.votenocharter.com, to spread their message. It includes video statements from critics of the charter, including Mielke and Yacolt Mayor Jeff Carothers.
