Clinton leads Donald Trump by 5 points or greater in POLITICO’s Battleground States polling average in Colorado, Michigan, New Hampshire, Pennsylvania, Virginia and Wisconsin. If the Democratic nominee won those six states, plus all the other reliably Democratic states President Barack Obama captured in both 2008 and 2012, she would eclipse the 270-electoral-vote threshold and win the presidency.

Even if Trump ran the table in the remaining battleground states — Florida, Iowa, Nevada, North Carolina and Ohio — he would fall short of the White House if he cannot flip another state where Clinton currently leads in the polls.

The six states where Clinton is currently comfortably ahead show all the hallmarks of swing states that have faded from contention. And Michigan, a borderline battleground state last won by Republicans in 1988, appears the farthest out of reach for Trump. The Democratic nominee has been ahead in every public poll in the state since the July convention, with the last four surveys indicating a double-digit lead.

The Clinton campaign has never even bothered to go up on the air in Michigan — and other than a brief flight in early September, neither has Trump’s campaign.
