Democrat Christian Menefee is projected to win the special House runoff in Texas� 18th Congressional District, according to CNN, further shrinking Republicans� narrow majority in the U.S. House. With Menefee�s expected victory, the chamber stands at 218 Republicans to 213 Democrats, leaving Speaker Mike Johnson with a razor-thin margin, able to lose only one GOP vote on party-line legislation once Menefee is sworn in.
