We begin with politics this morning as results command from some key primaries the Florida. Governor's race just made history and over an Arizona voters went the apples just days after losing their senator. John McCain we have team coverage this morning Terry Moran is in Phoenix and Karen Travers is at the White House force and Terry let's start with Florida walk us through these results. And why they're so important. Well this is the stunner of the evening American electorate always. Will throw out a screwball from time to time and this is it a big upset on the democratic side Tallahassee Mary Andrew guilin. Who wasn't given much of a chance one of his campaign manager said. That he was sure that no poll would show his candidate in the lead until the final poll Election Day and that is indeed what Japanese Bernie Sanders endorsed. Progressive Democrat. And he is going to square off against Ron Desantis. And he was a candidate on the Republican side who was nowhere in the polls just a few weeks ago and still. President trump tweeted his endorsement and Trump's domination of the Republican Party demonstrated once again. And Terry Condo in Florida with this microcosm of a politically divided nation increasingly defied. Democrats going left and getting the energy and the ideas on the progressive side. Gil and support Medicare for all and all kinds of things like that and on the Republican side. Pure from. For those who are centrist voters in Florida. I. There and a bit of a spot gets this is a polarized race in a polarized country. That means that the comment being Terry and Karen I want to bring you in your White House reacting to these results. I am president John is flat out DD about this win for congressman Desantis in Florida I expect we'll see the president down in Florida stumping for that candidate. Between now and Election Day presidents predicting. A big win for the Republicans in Florida governor's race and it carries at this somebody that he endorsed earlier this summer and that endorsement was huge for run Desantis. After the establishment Republicans were going for his rival over the last couple of months. Desantis is somebody that to say he cozying up to trump and transform our politics is probably understatement he ran an ad talking and its sign is child about building a wall in reading the art of the deal and really need that impact of rising from through cable outages the president discovered him worked for started seeing him. Doing hits on Fox News isn't anxiety really liked them a lot so now the president's office slamming Desantis is democratic opponent into Galen. He says this is aged rematch. Were Desantis. He calls gala may failed socialist and says he's not what Florida wants or needs. Well we'll find out soon enough let's talk Arizona now Terry I know that voters. Aren't. Filling John McCain's seat but the other seat up for grabs could be a critical one here. It could this is the seat that Democrats really have their I doubt they are looking at Arizona. Rapidly changing stayed in its demography as the best opportunity. To flip the state from red. To blue Jeff flake the incumbent Republican senator retiring and so the Democrats have nodded and nominated congressman. Congresswoman pierced in cinema she is inexperienced. Congresswoman who has run. Right to the senator in this campaign she made immigration and veterans affairs. Big big issue for. On the Republican side sheriff Joseph Arpaio was running Kelly ward is state senator Al who ran against John McCain and 2016 was running. They were they split the conservative vote and the establishment Republican candidate Martha Mexicali congresswoman from southern Arizona. She won with a majority she won a strong convincing victory solidifying the Republicans this race. So what the opposite the Florida race both candidates looking to the center. Both candidates sort of avoiding the extremes of their parties although Martha Mexicali got very very close to. President trump to win the Republican nomination she's already attacking a little but at the center. Maybe that is a legacy of the kind of the independent politics in this state. That brought the country John McCain and other people Sandra Day O'Connor for example at a rate is going to be one of the marquee matchups of these midterm elections these two women Arizona will elect its first woman senator squaring off in a state that is really at this point a toss. And Karen I wonder how the White House is reacting to this one's you know this Republican candidates in debate we're centers and the president but they seem to be allies at least so far. Apple endorsement from president from aunt later this morning from our the next Alley he called her. An extraordinary woman he says she's highly respected member of congress he cites her experience as a fighter jet pilot. He writes has my total and complete endorsement today he had waded into that primary which was notable given how we had other states. And any thought he had it might it push the race in a different direction he. Acting behind Kelly ward it really hard line or immigration Joseph Arpaio even very controversial pardon Q. Instead he stayed out of this but now keeping that full endorsement from Martha Sally. Another state where perhaps he could go to visit the president says he's going to be very active on the campaign trail between now and Election Day he once it said an all time record for the number of stops a president has done for his party. Big question is. Where can he go to be most helpful certainly sounds like momentary thing that airs on it by those candidates tacking to the center that's not ST perhaps he can make a big difference. Florida though one where he's certainly and it's very it does seem like Arizona's Hannity exception to the rule that we've been seeing a lot of these primaries where. A lot of winners are coming from extreme sides of the right and left what does this say about the future of our politics. Well voters want to shake things up on both sides they are tired of the consensus. Establishment politics especially the management of the economy. That essentially. Started in Bill Clinton's Arab all the way back to Reagan really where the investor class if you will we're dominating. These economic policy. Donald Trump is is may be a very wealthy man but is aid and economic nationalist economic populist and that has driven. The Democrats a little bit left as well they looked at the Hillary Clinton recipe for four economics they didn't like that what it says is. That voters. Are sick of the status quo and both parties they don't trust that they don't believe it's rhetoric anymore they didn't see the results of the economic policy or other policies. Still fighting with into the endless wars. They want change in both parties. And Perrier there and John McCain's home state yesterday senator Lindsey Graham. This really emotional tribute to him on the senate floor and others another tribute planned for today what's expected. Well this is an opportunity for Arizona to say farewell to one of her favorite sons just behind you can see. The preparation beginning. John McCain will be brought here by his family and that honor guard from the Arizona National Guard he will lie in state. Under the copper dome the Arizona State Capitol there they'll be. Private services and and the capitol building will be open. And arizonans by the thousands were expecting will line up and what is expected to be a hundred degree plus heat to say farewell to him it is as a sign of the respect across the party lines really in. Conversations we've been having over the past few days several people have said that I didn't vote form I didn't much like his politics at all. But I respected what he had done for the country and that. You know he did what he thought was right. It's a legacy that that lives on here and you'll see it. It in the way Arizona says goodbye to him here at the capitol and then tomorrow. There will be a funeral service where's Joseph Biden. A one of his long time. Democratic. Oils as if you will in the United States said they clashed. Plenty on national security and other issues when Biden was in the senate and when he was Barack Obama's vice president that they were. Very close friends indeed and it to sign. Of the kind of bipartisanship. That John McCain lift he fought his corner he was a fierce conservative on most issues but he was willing to cross the I'll. To get the business of the country Don and I think you'll see that reflected in. The way he is laid to rest of the next few. And certainly lead by example there and it's an interesting conversation every having at the same time.
