<p>President Donald Trump forecasted that Bernie Sanders would run against him in 2020 &#8220;even if he&#8217;s in a wheelchair,&#8221; and mocked the Vermont senator by imitating a scrunched-up body.</p> 
<p>Trump expressed that opinion over the summer when he invited four Democratic lawmakers to the White House, and also asked, &#8220;Who is going to run against me in 2020? Crooked Hillary? Pocahontas?&#8221; the <a href="https://www.nytimes.com/2017/12/09/us/politics/donald-trump-president.html?mtrref=www.google.com" type="external">New York Time</a>s reported on Saturday.</p> 
<p>At 70 years old, Trump was the oldest president to be inaugurated in the U.S. Trump, now 71, is nearly five years younger than Sanders, who would turn 79 in 2020.</p>

<p>But Sanders&#8217;s wife Jane in June said that the senator was actively advocating for policies benefiting the working class and that his age wasn&#8217;t a factor.</p> 
<p>&#8220;Ageism is the last &#8216;ism&#8217; that seems to be acceptable to people, and I never felt that it was whether somebody was too young or too old,&#8221; she told the <a href="https://www.nytimes.com/2017/06/13/us/politics/bernie-sanders-progressives-presidential-election-2020.html" type="external">New York Times</a>. &#8220;You win some. You lose some. And you keep on going and maybe you can win the next one.&#8221;</p> 
<p>Bernie Sanders, who lost the Democratic nomination to Hillary Clinton last year, has started addressing some of his political shortcomings including his lack of foreign policy connections, a sign he may be gearing up for a 2020 bid, <a href="https://www.politico.com/story/2017/11/27/bernie-sanders-2020-elections-258160" type="external">POLITICO</a> reported late last month.</p> 
<p>Other Democrats that Trump called out over the summer have not indicated they will make a bid for the presidency.</p> 
<p>After Trump in October tweeted he hopes Clinton will run against him, Clinton told BBC Radio 4, &#8220;No, I&#8217;m not going to run again,&#8221; but that she would continue to speak out against Trump.</p> 
<p>Massachusetts Senator Elizabeth Warren, who Trump refers to as &#8220;Pocahontas&#8221; because she claims to have a Native American background, is considered a top Democratic contender. In August, <a href="https://www.aol.com/article/news/2017/08/06/elizabeth-warren-says-shes-not-running-for-president/23067703/" type="external">she brushed off the idea</a>, saying, &#8220;I'm doing my job every single day. I am not running for president, I'm doing my work."</p> 
<p>Meanwhile, some <a href="http://www.newsweek.com/trump-2020-election-white-house-manafort-696089" type="external">Republicans recently have cast doubt</a> over whether Trump will seek reelection&#8212;even though he is raising millions of dollars for a campaign.</p> 
<p>New Jersey Governor Chris Christie in October told the Today show that if Trump runs again, &#8220;I would support him, yes, but I'm not so sure what will happen."</p> 
<p>Shortly after, Senator Rand Paul said Republicans "need to know (if) President Trump (is) running for re-election,&#8221; and, &#8220;I think you won't know that until you get into sort of second, third year of his presidency."</p> 
<p>Trump&#8217;s approval rating has remained very low as a probe into whether he and his campaign colluded with Russians in the 2016 election widens.</p>
