Sources
Verification note. Field dates, sample, weighting and verbatim wording read from the SLU/YouGov February 2026 topline PDF (items POLS035-POLS037); full favor/oppose/not-sure splits from that topline; party breaks from SLU's 'Missouri Voters' Opinions on LGBTQ+ Issues' summary PDF. NOTE: the summary PDF renders the stem as 'gender transitional medical care' while the topline prints 'gender transition medical care' - the topline wording is used here.
