president of the united states
is the most powerful job in the world so
which voters will decide who wins the
2020 election
let's take a closer look the u.s
population is estimated to be
330 million but only 245 million of
those are americans
over 18 who are eligible to vote that's
74 percent
if recent history is a guide only just
over
half of those are likely to turn out in
november's election
so we're down to about 140 million 42
percent of the population
however the u.s president is not chosen
by who wins the most votes nationally
it's actually a series of
winner-takes-all contests
in each of the 50 states most always
vote for either a democrat or republican
while some states lean towards one party
or the other in 2020
that leaves seven key battleground
states where the election will be won
and lost donald trump joe biden record
gains
the campaigns will be focusing their
attention and money
on voters here lucky them the number of
registered voters across those seven
states is 36.7 million that's just
11 of the total population
but experts say most of these registered
voters will never actually switch
sides at most 15 percent are potentially
persuadable that's 5.5 million voters
in battleground states or less than 2
percent
of the national population
the 2016 election proved how crucial
every vote in these places can be trump
won pennsylvania
michigan and wisconsin by a combined
total of 107
000 votes just 0.03 percent of the
population

and on the ground in michigan his margin
of victory came down to the equivalent
of just two voters per local precinct
in a close race the 2020 result could
come down to which candidate can
convince
a swing voter to switch sides or a
reluctant supporter
to turn out the world will be watching
