ESFJ is the commonest personality type on the MBTI. The Myers-Briggs Types Inventory is generally useful with regard to attitudes. The MBTI types individuals according to their self-report of preferential approaches to others and to information:
With regard to dogmatism (a feature of Republicans and the religious):
"A sample of 422 female undergraduate students, attending a university-sector college in Wales specialising in teacher education and liberal arts subjects, completed the Myers-Briggs Type Indicator together with the Troldahl-Powell Dogmatism Scale. The data demonstrated that higher dogmatism scores are most clearly associated with sensing rather than intuition. Higher dogmatism scores are also associated with extraversion rather than introversion, and with judging rather than perceiving. No significant difference in dogmatism scores were found between thinking and feeling."

That is, ESJ types are indeed more likely to be dogmatic. It's interesting that there was no significant difference in dogmatism between self-reports of T versus F.
E/I : extroversion vs introversion – outgoing, energized by social interaction vs introspective and fatigued by too much socializing.
S/N : sensing vs intuitive – satisfaction with the basic information (S) vs a tendency to search for cognitive insights based upon that information (N).
F/T : feeling vs thinking – self-perception of basing of decisions upon 'gut'-level intuitions and feeling (F) vs basing of decisions on logic and rationality (T).
J/P : judging vs perceiving – a preference for closed-ended structure and quick decisions (J) vs a desire to keep options open and to seek more information before making decisions (P).
Because the inventory is administered by fee-charging professionals who purchase it from the developers, it is not available on-line. However, it is not too difficult to quickly guesstimate where you – and your family and friends –would place on the inventory. This page has a chart with roll-over descriptions of each combination.
The four parameters yield 16 different combinations. Though many mental health professionals might treat these combinations as cut-and-dried, there are shades of gray to these parameters – for example, you might consistently base some types of decisions on feelings and other types of decisions on logic.
