This is our opportunity to build the most inclusive. Coalition. That we has seen in modern times but many are questioning if the country is ready for a gay president according to a Gallup poll that came out in January 21% of Americans said that they would not vote for a gay president does that number surprise you either being high or low. Don't but again I focus on the work. I focusing going out there and showing people who I had and I think we have an opportunity right now. To back in Americans to hire Collins. And to welcome people onto the right side history. Conservative radio show host Rush Limbaugh recently weighed in on the matter. They've got to be saying that despite all the great progress and despite all the great won't miss a despite all the great ground has been covered America's still we're not ready.

I dealt with a multitude of Rush Limbaugh's when I was walking through the hallway. As of my high school you sign. That Pete is ready to go toda told us president. But I'm more worried about the kids. I'm more worried about the people in this country who are watching how we treat. This candidacy cheetahs campaign and the way we treat people who for so long have been attacked by people like crush them on this president and I think. It is time bird moral leadership to be restored to the White House so when you are ready to share that deepest truth about yourself when you are ready to. Step out of the closet. He stepped out into something hopeful. An inclusive. And you look up to Washington see a president who cares about you and love scene. Chastain dissent. I grew up in a pretty socially conservative place I went to a school where you know if you were Tom the football team or are one of the jocks that. You know you are picked on and bullied and belittled being gay made things even harder. At one point you're homeless you know when I came out I was certain and I'd lose everything. I was so certain that I would be a disappointment to my feeling in my community in my church. And my friends. That rather than stick around and find out if there's going to be OK I ran away from and sometimes I slept on my friends' couches and floors and sometimes I felt like I was the burden even on my friend since I was just sleep in the back to my car but I had a happy ending that sorry I got to go home. I got to come home to two loving parents who were terrified for me. Because they loved me but they knew it was going to be hard. And it's I'm very very lucky not every kid has that story 40% of homeless youth in this country are LG BTQ. It was his own experience that shaped Chastain is work as an advocate for LG BTQ youth I have spent the last year traveling and meeting with. Kids all over the country. The last year alone I visited about a hundred LG BTQ senators and homeless service providers meeting with kids sharing my story and listening to there's. He says this election is not about policy for him it's personal. From homelessness to health care to the meat to movement Chastain says he can relate. Even were calling a time he says he was sexually assaulted when he was eighteen. I remember. Somehow feeling like my parents would be so disappointed in me. Ands. I don't know what it was about society that made me feel somehow that I had done something wrong. And to feel such shame and guilt. For somebody else taking advantage of me and it's I'm so grateful for everyone who has spoken out. Because it made me feel less alone two as somebody who held onto that for a really long time unfortunately that. That's shaped me in a really negative way trying to open up. While they Livan South Bend with their to rescue dogs Truman in buddy the campaign trail often keeps them apart. Unfortunately word we're not going to our home is much and so are.
