This is real — Nancy Mace did lose her primary badly (finished 5th), and Sarah McBridge did respond with that 'Happy Pride, Nancy' quip. Multiple outlets have it on record, including video. The post frames this as McBridge getting 'the last laugh' after Mace's well-documented campaign against trans rights. The headline leans celebratory, which is fair given the context — Mace had actively targeted McBridge, a trans congresswoman. One note: the 'devastating loss' language is a bit dramatic for a primary result, though finishing 5th is genuinely bad. The framing skips some broader context about why Mace lost (wasn't just the trans issue), but the core story holds up.
