Which Recent Presidential Nominee Ran the Worst Campaign?

[Landslide Lyndon]

Those who voted Clinton don't know what they are talking about. Take out Comey's letter (something over which she had no control) and the same people would say today what a well-oiled machine her campaign was.

Objectively Trump ran the worst campaign. He was an atrocious fundraiser, lost three debates hands-down, was constantly baited into saying dumb and/or offensive things, and changed three campaign managers.

9. Bush 2000 (Managed the Florida Recount perfectly. About the only thing he could have done better is played in more states ahead of time...but as he won Florida anyways, it doesn't matter)

You see, this is why I don't take seriously these rankings. Bush almost blew an election where he was ahead by double digits and had the active support of the "liberal" media.
During the last days he was campaigning in California while Gore had focused like a laser in Florida.
If it wasn't for Scalia and co. we'd still mention this as one of the biggest gaffes in presidential campaign history.

From worst to best.

1. Trump 2016 (If Russia hadn't stepped in, he likely would've lost in a landslide)

Them damn Russians and their Facebook ads. Deceiving the Rust Belt when Trump had a message tailor-made for them!

How obtuse are you? What influenced the election weren't the ads on Facebook but the groups purportedly ran by Sanders or minority voters which sowed constant division among Democrats and/or propagated Breitbart lies and smears. These were very effective according to every one who studied the matter.

2. First I'll give, but I would consider the second a narrow win and the third a tie.
3. It got him attention, right?

1) Nobody cares about your opinion, snap polls showed the vast majority of viewers declared her a winner in all three.
2)Following your logic the Stormy Daniels story would have gotten him loads of attention but for some reason Trump did everything he could to bury it.
