With only a month to go until the US election, Sky’s dedicated team of correspondents goes on the road to gauge what voters in key swing states make of the choice for president.         This week a series of unexpected events have been derailing the campaign. Iranian ballistic missiles poured into Israel, putting foreign policy at the top of the agenda at the vice presidential debate as Democrat pick Tim Walz and Republican JD Vance went head to head for the first time.     Plus, Martha Kelner and Mark Stone have been tracking the destruction of Hurricane Helene, the deadliest storm since Hurricane Katrina in 2005.   Will the destruction, and the response from the candidates, shift the polls in this key swing state?   Keep up with all the latest in our US election liveblog and check out the Sky News poll tracker. Producer: Rosie Gillott  Editor: Philly Beaumont  .
