I've lived in major cities and I've never seen homelessness like what I've witnessed in California. Regardless, they'll bring their ultra-liberal workers with them, who will vote for the same failed policies, making Texas a trash heap in the process.
Not necessarily. Here in North Carolina we've been the beneficiary of a huge exodus of financial and tech companies (tech operations to RTP and corporate/financial management to Charlotte). You'd think half of Charlotte is from New York and a good chunk of the RTP area is from northern New Jersey.
I moved to NC in the early 1990's just before this migration started. At the time it was wildly predicted that this would push NC into being a deep blue state but thus far (maybe twenty years down the road) this simply hasn't happened. This is in no small part thanks to the ludicrous jerrymandering the GOP has used as a poison pill against the Yankee invasion. But that was done well into this migration from the north. And running awful candidates has (John Edwards, Cal Cunningham to name two) hasn't helped the Democrats' case here.
Dunno why everybody assumed that just because you knew how to code or was a sysadmin Ninja you'd automatically vote Democrat. Turns out that isn't the case.
Voting patterns here tend to move more with overall demographics (age and race) more than anything else. And we haven't run out of angry white votes just yet.
And agree on the homelessness. I did a lot of travel to the Bay area during the late 1990's and into the first decade of the 2000's. The homeless situation was bad when I first started traveling there and got noticeably worse as time went on. Anyone who wants to talk about homelessness/mental health needs to spend some time on Telegraph Avenue in Berkeley.
