Question: It may seem as though the 2020 U.S. presidential election is a long way off. But good luck telling that to President Donald Trump or a dozen or so Democrats contemplating a White House bid two years from now.
Trump has already been out on the campaign trail testing themes for his expected re-election bid. "Our new slogan for 2020. Do you know what it is? Keep America great!" Trump told cheering supporters at a recent rally in Elkhart, Indiana.
But Trump also made it clear he is concerned about this year's congressional midterm elections, in which opposition Democrats are favored to make gains.

"And all of the great momentum that we are having as a country on jobs, on safety, on security, on our military — it is all at stake in November," Trump warned at the Indiana rally.

2020 is expected to produce a bumper crop of Democratic presidential contenders who will vie for their party's nomination. Those in the group range from the well-known like former Vice President Joe Biden and 2016 contender Senator Bernie Sanders of Vermont to a younger, less recognizable contingent that includes California Senator Kamala Harris and New York Senator Kirsten Gillibrand.
Several potential Democratic presidential contenders spoke about the party's future at a recent conference in Washington hosted by the Center for American Progress, a Democratic-leaning public policy institute in Washington.
Among the speakers was Massachusetts Senator Elizabeth Warren, who said Democrats face an uphill battle to win back control of Congress this year because of long-standing Republican advantages in winning a majority in the House of Representatives.
"We can't climb that hill by ignoring the millions of Americans who are angry and scared about the damage this president and this Republican Party have done to our democracy," Warren told the conference to a round of applause. "We can't ignore it and we shouldn't want to ignore it." Question: Who is Warren referring to when she says, "We can't climb that hill by ignoring the millions of Americans..."

Answer: democrats


Question: It has become increasingly common for academics to use social media to communicate with wider audiences. Twitter, like many other social platforms, typically measures success in terms of numbers of followers, likes and retweets, but this only tells us something about the spreading of messages but not necessarily whether the content of the messages is understood or embraced. One way to ascertain this is through network and language analysis, which, used together, can tell us how effective the communication is.
Economists tweet less, mention fewer people and have fewer conversations with strangers than a comparable group of experts in the sciences, and use less accessible language with words that are more complex, with more abbreviations and with a more distant tone. Their tweets are less personal and less inclusive than those used by scientists.
This is what appeared in April 2017 when we gathered data on tens of thousands of tweets from the Twitter accounts of both the top 25 economists and 25 scientists as identified by IDEAS and Science, including the top three economists at the time, Paul Krugman, Joseph Stiglitz, and Erik Brynjolfsson and, on the other side, the top three scientists, Neil deGrasse Tyson, Brian Cox, and Richard Dawkins. At that time those accounts covered roughly two thirds of all the following.
The timing is significant because 2016 has been declared the year of post-truth politics, the year in which appeals to emotions (pathos) superseded the significance of factual evidence-based information (logos), affecting people's constructions and interpretations of events. This has been accompanied by the growing prominence of political "alt" movements (e.g. UKIP, the Alt-right) and their aggressive, provocative, and populist narratives, and "fake news" leading to political shock events such as Brexit and the Trump election.
The relatively low traction of economists in these public debates has been and continues to be an important issue. Does the public not trust economists? Don't they understand what economists do and how they work? Is their work misrepresented in the media? And how do economists themselves interact with public opinion? Question: Who's tweets' were analyzed?

Answer: Paul krugman


Question: How long ago was it…? It was a long time is all I know. For my birthday, my parents took me and my brother out of school on the day before my birthday and we took a train.
(Funny interjection, my mom was caught on the wrong side of the station so she ran across the rails and was pulled up by my dad a couple minutes before the train came.)
It was a night train, so we had our own room where my brother and I claimed the top as our territory.
(Look at my younger self's squinty eyes… They are staring into your soul)
Anyways, it was morning by the time we arrived at where I would spend my birthday. Vienna, Austria.
I quickly got off the train in excitement taking in the view of the station like it was first time I had seen anything. We exited the station and took the trolley to get to our hotel. For breakfast, we had delicious, regional delicacies (among other things). They looked similar to crepes, but all I know is that it had a German name that I can't remember.
After we got situated in our hotel, we immediately headed off for the Mozart Plaza/Park.
My family and I also visited other monuments that day:
By the end of the day, our legs were worn out. We had rode so many trolleys and walked so much that I'm pretty sure that any longer and we would've collapsed on the spot. The bed never felt so good.
The following days we went to Austrian Castle, Ice Cave, and more buildings and such. The trip overall made this birthday the most memorable and the best thus far.
Bonus: We missed our night train back because of daylight saving hours. The trip back was definitely hectic, but adventurous. Question: Who had a birthday?

Answer:
the child
