Republican support for Donald Trump reaches new heights

Republican presidential candidates are converging on the snowbound state of Iowa for the first-in-the-nation caucuses. Former president Donald Trump has hit new highs in his polling lead over his opponents. A recent poll shows his support among Republican-aligned voters at more than 70 per cent. His closest rivals, Ron DeSantis and Nikki Haley, have a satisfaction rating of 61 and 48 per cent respectively. President Joe Biden has received considerably lower figures in a recent poll among Democrats with only 57 per cent of whom saying they would be satisfied with him as the party's nominee.
