Haley hopes to boost election bid with attacks on Trump’s and Biden’s ages

Candidate's ailing campaign will use mobile billboard in her home state to highlight her opponents' many verbal gaffes

Nikki Haley's Republican presidential nomination campaign in South Carolina is set to parade a mobile billboard drawing attention to rival Donald Trump's age on Saturday, as ageing and mental acuity issues continue to dominate the United States' political discourse.

The stunt, which was scheduled to pass through Myrtle Beach, comes as Trump begins campaigning in Haley's home state before the primary there on 24 February. It is scheduled to make stops outside a rally for the former president, according to the Hill, and show both Trump as well as Democratic incumbent Joe Biden appearing to fall into moments of confusion during public remarks.
