No, I don’t think so. Or at least, not to this extent. I would have no trouble voting for Eisenhower-era Republicans (mostly). Back in the 80’s they started the whole cut taxes, raise defense spending thing (and welfare queens were like the scourge of the country, those damnable single moms just ruinin’ everything) but to be fair Reagan worked with a Democratic congress and they did during various points in his administration raise taxes after the deficit started exploding (but it’s continued to grow at various rates ever since.)
The Heritage Foundation in the early 00’s began laying the ground work for ‘dynamic scoring’ and ‘tax cuts pay for themselves’ (I’ve linked their ‘analysis’ of the Bush tax cuts several times where they hilariously state the tax cuts would pay for themselves because of economic growth within three years, despite the CBO plainly showing otherwise. No surprise, the CBO was right.)
Although their ‘slide’ began in '64, Palin was the precursor, and 2010 is when they became what they are now IMO.
