millions of decent-paying jobs. enough is enough. >> reporter: sanders is trailing clinton in the polls, still he's beginning to resonate. is bernie sanders a real challenger for hillary clinton at this point? >> in iowa anybody can become a real challenger to the big establishment candidate. and that is why i think hillary clinton has to pay attention. >> reporter: voters in des moines say while it's still early they're listening. >> i want to hear how they're going to get these things done. how it's going to impact the middle class. >> i would love to see a woman as president. i know we can do it. >> i think it's time. >> reporter: now, clinton has nine campaign offices here in iowa. compare that to sanders who only has one. still after her bruising defeat in 2008 campaign officials say she can't take anything for granted. next stop, new hampshire. carl? >> nbc's kristen welker in des moines tonight. kristen, thanks so much. and those on the republican side are gearing up for a big announcement of their own after exploring a presidential run for months jeb bush will

vulnerable in our society should be in the front of the line not the back. >> reporter: a self-described introvert bush has not delivered the shock and awe jump-start the republican establishment had expected. jeb's presence did not scare off challengers. and he ran at donors with his fumbling response to the predictable question would he have invaded iraq based on what we know today. >> i would have and so would have hillary clinton just to remind everybody. i would have not engaged, i would not have gone into iraq. >> reporter: the family connection bush will highlight is his four decades with wife columba who was born in mexico. and bush will say the u.s. must do more to engage with the world. >> we can fix the problems that people think are intrabtible. with leadership we can move forward again. >> reporter: that last image you saw is the place where jeb bush will announce his presidential run tomorrow. advisers tell me that location sends a signal because miami-dade college is a diverse campus with students trying to

trapping people. and destroying much of the zoo. including this bear enclosure. in the chaos, this hippo swam out of his pen. zookeepers tried to save the other animals but there wasn't enough time. three of the zoo's staff died. >> it was really devastating. i can't say anything more. it was -- it was horrific. >> reporter: the zoo made headlines in 2013 after the birth of four rare white lions. the town's favorite famous for his friendship with a poodle, didn't survive. but rescue workers were able to save these two baby bears, several miles from the zoo. today, parts of the zoo are still intact. lions, a zebra, and other animals alive and well. along with a hippo, the massive mammal was tranquilized in the main square had a bite to eat, and was gently ushered back to a safe place. kelly cobiella, nbc news, london. with folks out

west dealing with one of the worst droughts in over a century, this week the white house said it's giving more than $100 million in aid to communities that have been hit. a portion of that money will go to help farmers whose businesses have been dealt a huge blow. nbc's hallie jackson has a closer look as part of our special series going to extremes. >> reporter: this morning instead of harvesting his asparagus, joe's ripping it out. why? >> because we don't have enough water for it. and we're very uncertain about what we're going to have next year. >> reporter: he's plowing under 155 acres. ironically on the same land president obama visited last spring. >> there's some huge demand for all this fresh produce. that's what i mentioned to the president. we produce healthy food that the first lady would like to see our children eetding. >> reporter: california grows the most asparagus of any state. the most broccoli lettuce and strawberries too. in all nearly half our produce comes from here. but this year growers will leave more than half a million acres

unplanted. about 7% of farmland in a state that feeds the nation. but even the president can't make it rain. >> i think it's important that all of us take responsibility, because it's not just california. >> reporter: the drought could drive up food prices nationwide about 2%. but its costs are much higher for farmhands. >> for somebody who's relying on summer work to get them through the year and it goes away then the food bank is the alternative. >> as you see -- >> reporter: food banks like this one in fresno, which president obama also visited. it's serving twice as many people as it used to giving out ten times as much food. to farm workers out of jobs, and out of options. >> the drought is really what we would consider a slow moving emergency. we're just going to have to find a way. >> reporter: a way to make it work, but for farmers like dell bosce, work is drying up. hallie jackson, nbc, california. when "nbc nightly news" continues on this sunday imagine
