GOP Senate candidate Mike McGavick -- who's battling to replace incumbent Dem Marie Cantwell -- has just propsed mandatory drug testing for all welfare-receiving parents, according to today's Seattle Post-Intelligencer:

In a speech to the Pasco-Kennewick Rotary, the former Senate aide and Safeco Insurance CEO proposed a "three-strike" requirement that could lead to mandatory drug-abuse testing and treatment, reduction of direct cash benefits and, in some cases, loss of parental rights...

McGavick's plan says that if recipients refuse treatment, cash benefits would be redirected from the parents to a third party. Continued refusal to accept treatment or repeated drug-test failures by the parents would result in removal of children from the home.

No word yet from Cantwell on McGavick's proposal.
