The US is bracing for protests, regardless of who wins today's election. 

The race between Kamala Harris and Donald Trump is expected to go down to the wire, with the final result being determined by key battleground states like Pennsylvania and North Carolina. 

Washington DC is installing reinforced fencing in the Capitol, over fears of protests if Harris wins. 

And former Democratic Party Treasurer Bill Derrough told Ryan Bridge there could be protests in Democrat strongholds like New York, if there's a Trump victory. 

He says that tensions are very high, and the rhetoric is very intense.
