The big talking points of the campaignThe big talking points of the campaign
There has been a slew of controversies generated by Donald Trump, from the moment the New York businessman launched his campaign with the description of Mexican immigrants as "rapists and criminals". His candidacy has rarely gone a few weeks without sparking some uproar. He's waged wars of words with a judge, a Miss Universe, a Fox News anchor and the Muslim family of a fallen soldier. He's had to defend his refusal not to release his tax returns and the suggestion he has paid no federal income tax for 18 years, plus field questions surrounding his charitable foundation.There has been a slew of controversies generated by Donald Trump, from the moment the New York businessman launched his campaign with the description of Mexican immigrants as "rapists and criminals".

And Hillary Clinton has had her share of anxious moments too. The damage wrought by her private email arrangement to her reputation is thought to be significant, despite the FBI effectively closing the investigation in July and clearing Clinton of wrongdoing. Questions have been raised about the foreign donations to the Clinton Foundation. Mr Trump has also put the spotlight on the part she played in pushing back at the women who claimed to have affairs with her husband Bill. And WikiLeaks has been revealing hacked emails that have laid bare some embarrassing conversations between members of her campaign team.And Hillary Clinton has had her share of anxious moments too.

The biggest bombshell to jolt the Trump campaign came on 7 October with the publication of a video from 2005. Mr Trump is heard referring to women in sexually offensive terms when he was caught on a live microphone during the filming of a soap. The furore forced him to issue an apology and try to convince voters that the words in the video "do not reflect who I am". But it wasn't enough to stop dozens of Republicans from deserting him, sparking civil war within the party. Now more half a dozen women have accused him of sexual assault, and he has hit back forcefully, accusing them of being liars and not attractive enough to warrant his attention.The biggest bombshell to jolt the Trump campaign came on 7 October with the publication of a video from 2005.

Then just 11 days before election day, the FBI announced it had found more emails "pertinent" to the Clinton email investigation, but could not yet say how significant these emails were. They were found on a laptop belonging to the estranged husband of one of Clinton's closest advisers, Huma Abedin, as police investigated whether he sent explicit text messages to a 15-year-old girl. These emails are now being looked at by the FBI to see if they include classified material or any evidence that their investigation into the emails was intentionally hampered.Then just 11 days before election day, the FBI announced it had found more emails "pertinent" to the Clinton email investigation, but could not yet say how significant these emails were.

Who won the debates? And what about policies?
ONE: New Yorker Trump landed some blows on Clinton on trade deals, her emails and the Middle East, framing her as a political insider who had achieved nothing after three decades of public life. But after a shaky start, she controlled the evening and he failed to stay disciplined about his message. The campaign has been consumed by controversy and the vote on Tuesday feels more like a referendum on the two candidates's personalities.
Who won the debate? But there are substantive differences on issues too.
TWO: Described as one of the nastiest presidential debates, repeated attempts at character assassination dominated. Mrs Clinton homed in on the 2005 video of Mr Trump's lewd comments about women. It showed, she said, "exactly who he is". Mr Trump held a bizarre news conference featuring Bill Clinton's sexual accuser and on the stage he focused on these allegations. The scandal over Mrs Clinton's use of a private email account for official business when she was secretary of state should land her in jail, the Republican candidate said. No knock-out blow from Clinton, says our North America reporter Anthony Zurcher, and it was probably a draw. Here's a full rundown on where they stand, and below is a look at what's at stake.
Who won the debate?
THREE: The most remarkable moment came when moderator Chris Wallace asked Mr Trump whether he would support the election results, no matter who won. Mr Trump refused to do so, going against a longstanding American tradition that the winner is recognised and congratulated by their rival. Instead, Mr Trump accused the media of poisoning people's minds and said Mrs Clinton should not have been allowed to run for president. At that point, the headlines were written and the debate results were locked in, said Zurcher. It was not a good night for the Republican.
Who won the debate?
VP DEBATE: The Republican vice-presidential nominee's primary job - really his only job - was to stop the bleeding and give the campaign an opportunity to regroup after Mr Trump's poorly received first debate. Mr Kaine's goal was to keep him from doing that. Mr Pence succeeded. Mr Kaine, while unloading a crate of opposition research on Mr Trump, failed, says Zurcher.

Both parties think they can bank on certain states, big and small. Republicans will count on Texas, and not waste their money campaigning to a great extent there. Similarly, California is likely to sit in the Democrats' column.Both parties think they can bank on certain states, big and small.

What about the US Congress?
The Senate election results will also have a big impact. Republicans currently hold the majority in the 100-seat chamber. But 34 seats are up for grabs on 8 November. Democrats need a net gain of four seats to win control of the chamber if Hillary Clinton wins the presidency, as the US vice-president is automatically a member of the Senate, and five seats if Donald Trump is victorious.
In the House of Representatives, all 435 seats will be contested. Republicans have controlled it since the 2010 mid-terms, and currently hold 247 seats, compared to the Democrats' 188. This means the Democrats would need to win 30 to regain control. A swing of this size is widely considered unlikely, though they may narrow the Republican majority.
