The Electoral College is tilted in her favor, and demographics are moving in the Democratic Party’s direction.
She’s running to succeed a popular president who is firmly on her side, and the economy is strengthening.
She’s also running against Trump, who has divided the Republican Party while alienating large groups of Americans.
Despite all those advantages, Clinton finds herself in an excruciatingly tight race.
As recently as Aug. 27, she had a more than 6-point lead over Trump in the RealClearPolitics national average of polls after a strong stretch following the Democratic National Convention.
On Tuesday, her lead was 2.4 percentage points in RealClearPolitics national advantage.
