Joe Biden tops key 2020 poll as he mulls whether he is too old to run for president
Joe Biden, Barack Obama’s vice-president, has emerged as an early frontrunner among Democrats vying for the 2020 presidential nomination with a dominant lead among voters in Iowa, who will be the first to state their preference next year.
A new CNN/Des Moines Register/Mediacom poll finds 32 per cent of likely caucusgoers saying they back Mr Biden as their first choice, ahead of 19 per cent for Bernie Sanders and 11 per cent for Beto O'Rourke, the telegenic campaigner who came close to an against-the-odds win in Texas last month.
