But then again once put into effect, the suburban Northeast turned from GOP to Dem. The GOP primarily won so handily pre-Reagan solely on taxes.
I agree with you, and I think that the GOP's embrace of trickle-down economics was definitely a factor. Many Republicans from the Northeast opposed trickle-down economics before Reagan, but then once they all started to support it, many Democrats began winning their seats over the next 30 years.
Well, pre-Reagan their taxes were still high, but now the Democrats seem to not want to hit those voters at all. Another factor is traditional white collar, college educated professions were generally immune to downturns at one time. Not anymore and even economically Northeastern suburban voters have moved left. I've said it before, you'd be more likely to find an urban white police officer in the GOP than an "office park" dad.
