Polls draw Joe Biden favourite for the Democrat White House Campaign

But concerns about the age of Mr. Biden and his gaffe in speeches have led the Democrats to question whether he would be the best candidate in front of President Trump in the upcoming year's elections.

In Arava, Mr. Biden aims to reinforce his status at the top of the democratic race, targeting President Trump.

If we give him eight years, and I believe that from the bottom of my heart, he will forever change our character and nature. So we must defeat Mr. Trump in 2020. ”

Mr. Biden remains at the helm of national and state surveys, but faces strong competition from several rivals, including Massachusetts Senator Elizabeth Warren.

“20 is our chance. We can make this government work for all of America. Democrats, let's do this. Work hard and win. ”

Despite his 76 years of age, Mr. Biden remains an energy politician. But it has also drawn criticism with a series of guilty ones, including comments on aid to the poor.

Poor kids are as smart and talented as white children, rich children, African American children, Asian children. ”

Beden has often been targeted by the man she wants to face in the election, President Trump.

Joe's short. This is not someone you can have as president. But if I get approval (of the Democrats), I'd be happy. ”

Biden has received several hits in the first debates, but has also shown renewed skills, says analyst Vanessa Beasley of Vanderbil University.

There is good evidence that the Democrats think he is the man with the best chance of defeating Mr. Trump. Many Democrats are showing tenderness because they want him to preserve the status of the most popular name and the greatest chance to defeat Mr. Trump. ”

The first votes between the democratic camp will take place in February what it means is that there is enough time for rivals to gain dominance, says Kyle Condick of Virginia University.

“Biden is leading as we approach September and October, and after some other debates he will prove to be the most stable leader of the race. But there's also a possibility that some of his supporters will get to the other candidates, and then we'll have a more open race. ”

The Democrats also remain divided over whether they should focus on Mr. Trump or on sweeping economic and social reforms, says analyst Darrell West of the Brookings Institute.

So the main current debate among the Democrats is taking place over whether they should seek small changes and essentially turn America into what was before Mr. Trump, or the need for more fundamental changes. ”

This dilemma will surface again when the Democrats hold their third debate next month in Houston.
