The 2020 US Presidential Election Entertainment Bets

As the law states, both parties have to undergo the selection of candidates who will represent them during the actual 2020 Election. 

Up to our surprise, there are many exciting props, especially on the Democratic-related markets.

With Donald Trump being backed up by the Republican Party Committee and leading the Republican nominee race at 1.07 (1/14), there is nothing much left to place a bet on. The opposite could be said about the Democratic Party nomination stage. You can take a look at the most interesting props offered by one of the top online bookmakers:

• How many times will Donald Trump tweet during the July Democratic debates?
  Over 12.5 1.50 (1/2)
  Under 12.5 2.50 (3/2)
   
• How many candidates will speak Spanish during the second round of Democratic debates? 
  Over 2 3.25 (9/4)
  Under 2 1.29 (29/100)
   
• Will Elizabeth Warren crack open a beer during the debate? 
  Yes 15.00 (14/1)
  No 1.01 (1/100)
   
• Will there be another mic issue during the debate which causes the moderators to cut to commercial break? 
  Yes 6.50 (11/2)
  No 1.10 (1/10)
