The US Congress is up for grabs in today's midterm elections, with Democrats eyeing up a potential double victory.

If secured, the party would be better placed to scrutinise President Donald Trump and block his plans.  

Polling predicts the Democrats have the House of Representatives in hand, but the Senate could be a tighter race.  

Former White House Spokesperson for George W Bush, Pete Seat told Mike Hosking he expects the Senate will come down to one seat, but some think it could be split down the middle.  

He says if that happens, it will have a fascinating impact on JD Vance's potential presidential campaign, because he'd have the tie-breaking vote as Vice President.
