Roughly 950,000 Republican and Democratic voters cast ballots across Texas in party primary runoff elections on Tuesday. On the GOP side, Tea Party candidates did extremely well at the top of the ticket while establishment Republicans did better in downballot legislative races. Democrats, meanwhile, avoided major embarrassment by not choosing an advocate of President Obama's impeachment as its U.S. Senate nominee. But Democrats also nominated for ag commissioner someone who promises not to campaign for the office.
