Lol! Pete Wilson rode the coattails of Prop 187 to his last election. After which he was term-limited out of office. His last-minute support of Prop 187 helped him win the election, and cost him exactly nothing at the polls- Prop 187 was passed by over 60% of the voters.
I don't know what lesson you think he "learned", but it sure isn't that California voters are unconcerned about the border. Wilson is unapologetic for his support of Prop 187, although I've sure read a lot of ignorant drivel by East Coast "experts" who apparently no nothing of what actually goes on in California.
And replaced by a Dem.
