Republican Ken Paxton heads into the final stretch of his pivotal Senate race without having closed a GOP enthusiasm gap that’s complicating his path to victory and the party’s control of the upper chamber.

Near-unanimous support for Democrat James Talarico within his party and a sizable chunk of GOP crossovers offer a window into the state representative’s minor, although steady, edge in the polls as Paxton continues to struggle with coalescing Republicans. Polling consistently puts him at under 90% among Republicans, leaving on the table crucial voters who either pick Talarico or decline to side with either candidate.
