I would guess that the interests of SMB owners for US residents and expats differ. SMB owners in the US probably think more short-term and think that policies from Trump will help them (which they may, but will ultimately continue the steady decline of the US workforce, e.g. lack of a social safety net, upward mobility, lack of education, a broken patchwork of poorly-maintained car-centric infrastructure).

SMB owners who are US citizens abroad, however, are driven by primarily one thing, regardless of party affiliation: who will be most likely to support a rewrite of the punitive tax laws that the US places on its expatriate citizens (which no country other than Eritrea does).
