Yes, this account is based on real data. The article which explains the idea behind the bot can be found here, and the GitHub project here. In particular, the following extract is relevant:
We created a Twitter bot and dubbed it “@American__Voter” (a nod to
another seminal and related study) that uses data from the 2016
Cooperative Congressional Election Study, a nationally representative
survey of 64,600 American adults, to fuel the bot. Every hour, a
computer program running the account (1) randomly selects an
individual who took the survey, (2) selects 3 various issue positions
held by the individual, (3) and spits out the individual’s party,
self-described ideology, and those 3 policy preferences in one
Sometimes, the voters profiled by American__Voter will make “logical”
sense: for example, a voter will support both gun control, the
affordable care act, and oppose immigrant deportation, all of which
represent liberal attitudes. But that’s not what makes it interesting.
Rather, we are interested in those less “constrained” Americans.
The tweet you've picked out is an example of one of those "less constrained" Americans.
If we look at the dataset, we can confirm that an individual exists. The main dataset contains 64,600 individuals. This then breaks down as follows:
7,926 out of 64,600 respondents picked 'Black' when asked "What racial or ethnic group best describes you?"
Of these 7,926, 2,789 identified as Male.
Of these 2,789, 55 were born in 1954 (looking at the code, age is calculated as
Of these 55, 31 had a college degree.
Of these 31, just one identified as either a 'Lean', 'Not very strong', or 'Strong' Republican.
This individual voted for Trump in 2016 (question CC16_410a), opposes the Clean Air Act (question CC16_333d), supports concealed-carry (question CC16_330e), opposes always allowing women to obtain an abortion as a matter of choice (question CC16_332a), supports eliminating mandatory minimums (question CC16_334a), and is registered to vote in Virginia according to Catalist.
So this voter in particular does exist, or at the very least, a CCES respondent reporting this data exists.
