A prediction that the US southern border will be a big issue for both political parties. 

Joe Biden has been struggling to get a border deal over the line, facing impasses from Republicans over aid to Israel and Ukraine. 

But Donald Trump also has a challenge stemming from inaction on it when he was in office, as well as trying to insert himself into negotiations. 

Former Republican Communications Director Doug Heye told Mike Hosking that in trying to campaign on the border, Trump has potentially gifted Biden. 

He says Biden is looking for anything to hang his hat on, and saying Trump doesn't want anything to happen for political reasons is giving him hope.
