According to US expert Andreas Utterström, the vice presidential candidates' task is primarily to be a support.
- The moment you are elected vice presidential candidate, you have to put your own opinions aside.
The most important thing is that you are a good "sidekick", do not shine too much and stick to the message.
Both Harris and Pence are more experienced politicians than Barack Obama was when he was elected president.
Months for cooperation
In Trump's case, it's a lot about himself, his leadership and his appearance, says US expert Frida Stranne
-I think Joe Biden will be more concerned about the collaboration with Kamala Harris than Donald Trump is with Mike Pence.
But Trump needs Pence to address the conservative Christian voters who had concerns about Trump's life and living, she says.
More civilized
The debate between Joe Biden and Donald Trump went down in history as a chaotic event according to many commentators.
The question is how will it be this time?
- The debate between Harris and Pence will be more civilized than the one between Biden and Trump.
Many praise Kamala Harris as a good debater, but there is a risk that Harris will be over-ignited and overly aggressive and that Pence, who is calm and objective, will get the viewers' sympathies.
Expectations of Harris are high and that speaks in Mike Pence's favor, says Andreas Utterström.
