Based on what he's said, he's basically a straight-line conservative and he doesn't get sucked up into identity politics. That doesn't completely match up with my views, but it's good enough for me.
It is fascinating to me how the meaning of "straight-line conservative" has evolved in my lifetime, particularly in regards to social issues but lately in regards to economic issues as well. The reason I voted for Republicans consistently for a majority of my life is because they tended towards fiscally responsibility, advocated for free trade, and supported building and maintaining international coalitions. The advent of the Moral Majority altered the fabric of the Republican party and "conservative" became a social label, as well as an economic one. I'm still an old school conservative economically but I am in firm disagreement with "social" conservatives on a majority of issues. Fortunately the northeast US still has a few socially liberal, economically conservative Republicans like Larry Hogan and Charlie Baker, who, incidentally, are two of the three most popular governors in the US. If either of them attempted to run for office in the deep south they would be tagged as socialists.
Ben Watson has been firm in his support for "Focus on Family". This organization was created by James Dobson, a man who suggested killing trans people and has spent his career fighting against homosexuality. Focus on Family supports abstinence only sex education, an absurd position that directly leads to more unwanted pregnancies and abortions, something this organization wants to end. It is literally counter productive. Focus on Family also is against almost all LGBT rights, including marriage and adoption. Focus on Family also support teaching creationism in school. They are also against many "sins", including gambling, pre-marital sex, divorce, "drugs" (including marijuana), and porn.
The most disturbing position of Focus and Family has been their consistent moral and economic support of gay "conversion therapy". Focus on Family has sponsored conferences world-wide on the subject and backs the practice. Gay conversion therapy is regarded by every major medical association in the western world as not only detrimental to gay people but actual torture. It has been banned in nine countries and that number is growing yearly. It is not just ignorant but is cruel and unjustifiable morally or ethically.
When Watson appeared on Fox News to defend his support of Focus on Family after Dree Brees had disavowed his association with the organization on discovering that anti LGBT and supportive gay conversion therapy information were easily seen on their website and advocated by their founder, Watson decried these descriptions as "scandalous" and "misleading".
"When asked how he thought critics were lying, Watson said “labeling Focus on the Family as anti-gay, anti-nondiscrimination.”
Obviously, Ben Watson either refused to actually read the website before or after associating with them or he supports their positions and protects them through dissimulation. Either way, his actions are reprehensible.
Whether that should preclude people from voting for him depends on your personal beliefs. Support for Focus on Family and the torture of gay people has not stopped Mike Pence from becoming the vice president.
