After a blockbuster first round of debates between Donald Trump and Hillary Clinton, it’s now the vice presidential candidates’ turn in the spotlight. Tim Kaine and Mike Pence will be facing off in a debate on Tuesday, the only debate between the running mates compared to three total debates between the presidential candidates.

The debate surely won’t draw the incredible audience of 84 million that Trump and Clinton enjoyed, but it will certainly be much more watched than past vice presidential debates. It is certainly likely to be a less fiery affair, with both Kaine and Pence seasoned politicians who have governed states (Kaine governed Virginia, Pence governed Indiana). They are both likely to be much more polished than Donald Trump.

But the issues they fight over may be similar, and both will probably be raked over the coals over their partner’s faults. Pence is likely to go on the offensive about Clinton’s email scandal, while Kaine is likely to attempt to paint Pence into a corner over some of the controversial things that Trump has said and done, forcing him to either back the unpopular things the candidate has said, or contradict him.

Unlike Clinton and Trump, Kaine and Pence are relative unknowns, and this is their chance to educate the American public about who they are. Whereas Clinton vs. Trump was the battle royale, Kaine vs. Pence is really an introduction for the first time for much of the American public.

This will be the first nationally televised debate for either Kaine or Pence.
