Weekend Insider: Primary Fights

Ahead of the May 29 primary, we look at two races in Texas: state Rep. J.M. Lozano's fight to keep his House seat, and former Dallas Mayor Tom Leppert's bid for the U.S. Senate. 

Lozano was elected in 2010 as a Democrat — but switched parties 15 months later. Despite praise from GOP leaders for sticking to his principles, Lozano is facing a formidable foe in his primary re-election bid. Is the party over for him? 

Leppert became mayor of Dallas in 2007 — focused, he said, on fixing the city’s problems, not higher office. But near the end of his term, he resigned to run for the U.S. Senate. While Leppert has accomplishments to tout from his time at City Hall, he also faces critics who say he never gave the job the attention it deserved.
