The race for Texas attorney general is tightening in both parties as early voting approaches in the state’s primary elections, according to a new poll. In the Democratic primary, state Sen. Nathan Johnson (D-Dallas) holds a narrow lead over former Galveston Mayor Joe Jaworski, 25% to 22%, in a survey conducted by political scientist Mark Jones. The poll shows a large share of voters still undecided, suggesting the contest remains fluid in the final days before ballots are cast.
