The political blog Wonkette cites Representative Steve King (R-Iowa), with the worst metaphor of the day.
Quoting from the Sioux City Journal: A transcript of King's comments made at a Republican fundraiser in Boulders Conference Center showed he compared "illegal immigrants" to stray cats that wind up on people's porches. King said at first stray cats help by chasing mice, so people feed them. King added that the stray cats then have kittens, which are liked for their cuteness, but eventually the strays, fed by the people, end up getting lazy, just like illegal immigrants. King would not comment on what he said on that day.
Contact Congressman Steve King and express your disapproval of this metaphor. Remind him that immigrants are human beings with unviersal human rights.
