Happy new year! It’s January 1st 2020 and now that 2019 is over we can start properly counting down to the first big electoral event of the year: the Iowa Democratic Caucuses which take place on 3rd Feb.
So far Bernie Sanders has spent approximately $16.5 million on advertising; this is a sizeable chunk more than his left wing rival Elizabeth Warren who has spent around $10.7 million on ads, but less than Pete Buttigieg whose ad spend is about $20 million.
All three are dwarfed by Michael Bloomberg and Tom Steyer, two billionaires in the Democratic contest, who have spent around $100 million each so far on advertising.
