Joe Scarborough compares <a href="http://www.realclearpolitics.com/video/2016/06/28/full_replay_donald_trump_policy_speech_on_trade_reform.html">Donald Trump's address on trade and economic policy</a> and <a href="http://www.realclearpolitics.com/video/2016/06/29/trump_chamber_of_commerce_controlled_by_special_interests.html">a campaign rally he held in Bangor, Maine</a> Wednesday where he <a href="http://www.nbcnews.com/politics/2016-election/donald-trump-wants-consequences-gop-rivals-not-endorsing-him-n601406">denounced the "sore losers" in the Republican race</a> who refuse to honor their pledge to endorse the party's eventual nominee. Scarborough said Trump seems incapable of being a disciplined candidate and moving on. "The stupidity is breathtaking," Scarborough said on the Thursday broadcast of MSNBC's <i>Morning Joe</i>. "The stupidity is breathtaking. Here you have a guy that <a href="http://www.realclearpolitics.com/video/2016/06/28/full_replay_donald_trump_policy_speech_on_trade_reform.html">delivers a speech that actually can convert Democrats</a> in Ohio and Pennsylvania and across the rust belt. "<a href="https://www.youtube.com/watch?v=2jCmR-dqxvA">And then he goes off on GOP candidates</a>," Scarborough said. "They're not going to endorse him now. He keeps knocking them around like that, that's the last way to get people to endorse you." Scarborough said this shows Trump is obsessed and undisciplined because no one cares, including Trump, if he gets the endorsement of Jeb Bush or John Kasich. "Who cares? Who cares if Jeb Bush endorses him? Who cares if John Kasich endorses him? He's obsessed -- it's like when he was ahead in 49 states in polls, but just losing in Iowa. He went to Iowa and <a href="https://www.youtube.com/watch?v=PRUc11fPAwk">called people in Iowa stupid</a>. I wonder why he lost in Iowa. He said, what are you stupid? The guy, is he capable of being disciplined and moving on or not?" Scarborough asked. "There's got to be consistency every single day," Scarborough hammered. "If he doesn't have the discipline to do that every day, Hillary Clinton's going to blow him out. If he had the discipline that <a href="http://www.realclearpolitics.com/video/2016/06/28/trump_clinton_globalist_friends_want_to_scare_american_people_out_of_voting_for_a_better_future.html">he showed in Pennsylvania</a> and <a href="http://www.realclearpolitics.com/video/2016/06/28/trump_tpp_trade_deal_another_disaster_pushed_by_special_interests_who_want_to_rape_our_country.html">in Ohio two days ago</a> and if he carries that over the course of the campaign, this is going to be an incredibly fascinating race." Transcript: <blockquote>SCARBOROUGH: If you're going to turn the page, Mika, you have to turn the page. You've got to unite the entire Republican party and then you've got to move forward. You can't have one day, I'm going to read the teleprompter today and then the next day go, 'I'm going back to July of 2015.' There's got to be consistency every single day. If he doesn't have the discipline to do that every day, Hillary Clinton's going to blow him out. If he had the discipline that <a href="http://www.realclearpolitics.com/video/2016/06/28/trump_clinton_globalist_friends_want_to_scare_american_people_out_of_voting_for_a_better_future.html">he showed in Pennsylvania</a> and <a href="http://www.realclearpolitics.com/video/2016/06/28/trump_tpp_trade_deal_another_disaster_pushed_by_special_interests_who_want_to_rape_our_country.html">in Ohio two days ago</a> and if he carries that over the course of the campaign, this is going to be an incredibly fascinating race. SCARBOROUGH: The stupidity is breathtaking. The stupidity is breathtaking. Here you have a guy that <a href="http://www.realclearpolitics.com/video/2016/06/28/full_replay_donald_trump_policy_speech_on_trade_reform.html">delivers a speech that actually can convert Democrats</a> in Ohio and Pennsylvania and across the rust belt. And then the next day -- because he's talking about people -- he's talking about other people's jobs and bringing jobs back to America. He's not obsessed with the minutia of politics. <a href="https://www.youtube.com/watch?v=2jCmR-dqxvA">And then he goes off on GOP candidates</a>. They're not going to endorse him now. He keeps knocking them around like that, that's the last way to get people to endorse you. But who cares? Who cares if Jeb Bush endorses him? Who cares if John Kasich endorses him? He's obsessed -- it's like when he was ahead in 49 states in polls, but just losing in Iowa.
