The most spectacular evidence of this is the disastrous damage the Republican Party did to itself in California in 1994 with its support of Proposition187.
The Republican Party in California has been a permanent minority party since 1994 when it backed Proposition187, a law nearly identical to the Arizona Republican adopted last year.
The Supreme Court found a similar Texas law unconstitutional in 1982, and a comparable California law, Proposition187, was passed in 1994 but got tangled up in the courts.
