Howe Joe Biden Could Blow It

Recent polls indicate that President Donald Trump is losing his bid for re-election.
There are still four months before the election.
According to Politico there are several ways challenger Joe Biden can blow the election.
Biden might say the wrong thing at a debate.
He might have an awkward moment in an interview or at a press conference.
Trump’s massive advertising campaign might begin to resonate, hurting Biden’s favorability ratings.
Biden’s campaign might make poor decisions about spending allocations in the battleground states.
The media coverage of his campaign may sour if he loses even a percentage point or two in polls.
Presidential candidates with large leads have all suffered from less.
