October 16 , 2017 - The first wave of 2020 presidential campaign buttons have arrived at campaignbuttons-etc.com. While President Donald Trump has already indicated he will run for re-election in 2020 lets take a look at who might be the potential Democratic Party presidential challengers to appear next on a campaign button.

First up would have to be Senator Bernie Sanders of Vermont. While Sanders came in second behind Hillary Clinton in 2016 for the race for the Democratic nomination he still tops most lists of potential 2020 Democrats. While not yet indicating if he will run in 2020 , Sanders continues to appear around the country and recently touted his Medicare for All plan.

Senator Kamala Harris of California first elected to the U.S Senate in 2016 , often appears in the top 10 of potential Democratic party presidential hopefuls. Before being elected to the Senate , Harris served as the Attorney General of California from 2011 to 2017.

From New York comes Governor Andrew Cuomo. First elected governor of the Empire State in 2010 , Cuomo will be seeking a third term as New York Governor  in 2018. Prior to becoming  Governor , Cuomo was elected New York State Attorney General in 2006.

Senator Cory Booker of New Jersey , known for his savvy use of social media , is also considered a potential 2020 White House candidate. Hillary Clinton considered Booker  for her vice presidential running mate in 2016 before eventually settling on Senator Tim Kaine of Virginia. Prior to his being elected to the Senate , Booker served as the Mayor of Newark , New Jersey from 2006 to 2013.

Another top 5 contender for the 2020 Democratic Party presidential nomination is Senator Elizabeth Warren of Massachusetts. Though Warren has said that she is not running for president and is instead focusing on winning reelection to the U.S. Senate in 2018, if she were to run she would fine a lot of support from the progressive wing of the party.

Though probably to young at age 37, Congressman Joseph P. Kennedy III of Massachusetts is sometimes mentioned as a possible future presidential candidate. While 2020 may be too soon for him, Kennedy is sure to pop up on the short list of possible vice presidential running mates for any 2020 Democratic Party presidential nominee.
