Julián Castro is bringing an end to his bid for the presidency. The former housing secretary and only Latino candidate in the Democratic nomination race has struggled to make a breakthrough in the polls during his year-long campaign. “I’ve determined that it simply isn’t our time,” Castro said in a video message posted to social media by his campaign Thursday morning. “Today it’s with a heavy heart, and profound gratitude, that I will suspend my campaign for president.” He added: “I’m not done fighting... I’ll keep working towards a nation where everyone counts, a nation where everyone can get a good job, good health care and a decent place to live.” He gave no indication of his immediate plans and didn’t endorse one of the remaining candidates. Castro rarely scored more than 2 percent support in national or early-voting state surveys and, although he took part in the first four primary debates, he has failed to make the cut for the ones that followed.
