Eh, not necessarily. I can't count the number of times a Republican's resume got blown up in spectacular fashion. Guys claiming to be SEALs when they burned out of basic training. Electrical engineers actually being technicians but demanded having "engineer" in their official title. Claiming to have worked for so-and-so and when someone actually does the digging, they'd never heard of him.
Have you been to Texas? It's the ultimate poser state, at least in the deep red districts. If you want acceptance it's all about where you live, what you drive and how much you make. There's immense social pressure to wildly exaggerate your resume, even if you're retired if you want an invite to your neighbor's next barbecue. These people (who are judgmental as fuck so they're most certainly not exceptions to what I'm saying here) live in ranch homes near Houston. You think a former NASA engineer couldn't have done better than that? Especially if it's some jackass who judges others on how financially successful they are. These people live in the absolute biggest house in the most expensive neighborhood they can barely afford and often beyond what they can afford. Which, in this case, for an engineer that a high tech firm in any era would practically offer sexual favors to hire, is a ranch home outside Houston.
They're not poor, no. But they're not smart, and their claims can't be trusted. Not when they're living their own image of what stupid people think smart people are like.
Edit: FWIW, most actual engineers I've met in just about any state are Republican. But I'll take any bluster out of Texas with a grain of salt. "Worked AT NASA", as opposed to for NASA, is an interesting choice of words.
