AZ is a good example. Hayworth campaigned/lost on enforcement only. His opponent campaigned/won on enforcement, guest workers, and amnesty
"The 2006 exit polling confirmed the RNC memo."
Which exit poll? Conducted by whom? The RNC?
Oh, really? Here is a anti-Hayworth Mitchell ad , that mentions everything but Hayworth's immigration stance. I don't think you can show me any pro-amnesty Mitchell material. So too can I show you a zillion anti-amnesty ads by putting "immigration ad" as a search at YouTube . I doubt you can show me a single pro-amnesty 2006 election ad.
The GOP memo you tout...
The public wants a comprehensive solution that includes reform on three fronts: (i) strengthening border security/law enforcement to stem the flow of illegal immigration, (ii) enhancing the avenues through which immigrants can lawfully and safely enter the U.S. for work and (iii) creating a compassionate, practical and equitable way for those illegal immigrants already in the U.S. to legally enter the system [i.e. amnesty].
...claims that the electorate wants amnesty, but no one heeding the memo dared put it into their ads. By becoming unpopular, Bush pooped in the GOP punch bowl, resulting in GOP defeat. You go poking around among the many fallen and cry "See here, a border hawk!" It proves nothing.
Bush was prominent in his pro-Amnesty stance. If he had been on the ballot would he have fared better than the anti-illegal GOP congressmen?
I know, just look at those referendums they passed.
