I agree, Trump started the midwestern strategy, which will bring midwestern whites to vote for the GOP by the same margins southern whites do, not the western strategy.
In Washington/Oregon, this will happen only after liberal overreach turns the PNW into another rust belt and they see the socialist "paradises" of Seattle and Portland morphing into new versions of Crimecago, Deathtroit and Theiveland.
California will be free from it because that will basically become Northern Mexico in a decade.
Seattle's economy is expanding so rapidly that labor economists (by accident) found that the minimum wage increase drastically reduced the number of "low wage" working hours because the number of jobs that pay above 19 dollars an hour has increased a break-neck pace. It's attracting migration from all across the country and around the world for obvious reasons - Amazon is located in Seattle, Microsoft is located within the metro area etc. Because Amazon is a retailer, it offers services that are non-tradeable so there's little reason to believe that it's function as a distributor will be rendered obsolete anytime soon or that significant outsourcing will occur etc. In otherwords, Seattle's future is one in which it will almost certainly be a Great American City.
Everything written about Seattle could be said about the Bay Area.
There are gross inequities that have been generated by the innovation that has taken place on the West Coast but it's rather clear/obvious that this innovation has taken place due to immigration (Elon Musk is an immigrant), the financing of world-class public universities and labor law that protects employees such that "non-compete" contracts are outlawed, allowing workers to seamlessly flow between firms, allowing for spillovers.
As far as your racist anti-Mexican sentiment is concerned, you are aware that immigrants come to the US because wages are much higher here, right? If convergence is taking place - and it has - immigration will cease - and it has. The convergence has occurred because northern Mexico has become wealthier as it is a center of both light and advanced manufacturing so the movement of industry to Mexico and the creation of supply chains between the US and Mexico has reduced immigration. This shows that everything spoken about and written about by your leader is a bald-faced lie. He is a con-artist.
