So what exactly happens if Trump won't concede?

[Inmate Trump]

The idiot may not accept the results but what does that really accomplish for him?

[MasterJedi]

Arrest him and charge him with treason.

[GeorgiaModerate]

None.  The electoral college will meet in December and cast their votes, which will be opened and counted by Congress in January, and Clinton will be inaugurated on January 20.  There's nothing official about a concession speech.

[Darthpi – Anti-Florida Activist]

Arrest him and charge him with treason.

No. Not unless he directly encourages armed resistance. We shouldn't jail someone just for being a jackass.

[Ronnie]

Republicans continue to be filled with rage, and the rest of the country moves on.  In other words, not a whole lot changes.

[Erich Maria Remarque]

Arrest him and charge him with treason.

No. Not unless he directly encourages armed resistance. We shouldn't jail someone just for being a jackass.

What about indirectly? Like "Second Amendment People... blah-blah-blah... will fix it..."

I guess nothing until something happens and then something happens to him. That is when being a jackass becomes Solicitation.

There was an article in the NYT on this topic. I can't post links yet, but you can google the title:
Could Trump Reject the Election Results? Yes. Would It Do Any Good? Nope.

What do you mean? I think that Trump and Hillary are pretty well-guarded.

If someone is capable to start a sort of "civil war" it is Trump. Even though the probability of it is extremely low <1%, it is not unexistable.

[ProudModerate2]

We just all flip-him-the-bird, then ignore him and life goes on.

[Likely Voter]

After election night states continue to count votes including provisional ballots and a couple weeks later the Secretary of State for each state will certify the result and the appropriate 'electors' (of the Electoral College) are notified. On December 19th in each state the electors cast their official votes, those are then sent to the US Congress. On January 6th the votes are officially counted and the winner determined. On January 20th the inauguration is held.

What a candidate says (about concessions or rigging or space aliens) doesn't matter, the process will continue. However, candidates can submit lawsuits to effect how votes are counted and to try and stop the process, but such a lawsuit would have to have merit.  

However, there is one thing a concession does seem to effect and that is the official Office of Transition set up by the US Government. By law the winning candidate is given office space and money to manage the transition. The "apparent winner" is determined by the head of the GSA and this is ususally done the day after the election. The one time it wasn't done was in 2000 and the head of the GSA at the time said that until one party conceded, the GSA could not start the transition process. This was a judgement call and 2000 was very close, so the head of the GSA could use that as precedent or just decide to determine Clinton the winner if it seemed clear she was the winner and Trump was just being a sore loser.

I suspect that if Trump refused to concede and the election were not close (with recounts) then Mike Pence and Reince Preibus would concede on his behalf. And that would be that.

The Supreme Court standard established in Brandenburg v Ohio for limits on freedom of speech is speech that incites "imminent lawless action." Now, there is an interesting discussion to be had about whether or not that is the right standard, but as of right now that is the standard.

[ursulahx]

A satirical radio programme on the BBC tonight joked that Trump might just crash the inauguration and try to take the oath. Then Clinton would walk into the Oval Office on Day One and find him sitting behind the desk.

A concession is basically a promise to not launch a lawsuit regarding the election. The lack of one doesn't nullify the election or change anything at all. The only thing Trump could do is go directly to the D electors and try to get them to break their pledge to vote for Clinton, but that has like a 0.00000001% chance of working unless it is a 270-268 or maybe 271-267 scenario.

Haha, he will just creepily be lurking like this:

It wouldn't affect the outcome of the election, but it could encourage his supporters to stage protests, which might become violent.

How come then he get away with "I'd punch him in the face" and Second Amendment People. Trump is pretty good to send unclear messages.
In if he'd be arrested, it could start "chaos" as well...

[Hermit For Peace]

LOL! Give him the hook!!!

We're going to have TEA Party x100 with guns regardless of anything Trump says or does.

If you are enough of a meathead to go carrying AR-15s into Best Buy, you're enough of a meathead to gather with hundreds of other AR-15 open-carriers on the National Mall.  This is gonna get ugly.

I am just saying that he might be indicted for Federal Solicitation if someone was killed because they rioted directly because of what he has said.

Beyond that, all of this stuff being said here probably happens.

[mark_twain]

Even if Trump does not concede, the major media networks will still declare a winner, based on each state's vote count and resulting electoral vote count of each candidate.

Clinton will then give a victory speech based on the vote count, regardless of what Trump says, and she will begin the transition of power from Obama's administration.

Trump's refusal to concede will effectively be merely a sideshow, further highlighting his stupidity.

[longtimelurker]

There will be numerous internet memes with Trump as the Black Knight from Monty Python and the Holy Grail.

[HisGrace]

As others have said, there is no legal significance to conceding. It is just considered in good taste. Trump will just look like more of a baby than he already does.

[Absentee Voting Ghost of Ruin]

The idiot may not accept the results but what does that really accomplish for him?

He could manage to get himself shot while resisting arrest for preaching sedition. Then he'd never have to live with being The World's Biggest Loser AND he'd go down in alt-right history as a martyr.
