US presidential candidates vying for their party nominations are toning down attacks against their rivals opting instead for messages of reflection on the morning of the country’s Iowa caucuses.
Speaking to US broadcaster NBC, billionaire Donald Trump declined to predict the outcome of the caucuses, noting that fellow Republican Senator Ted Cruz is “a talented guy”.
On ABC’s Good Morning America, Mr Trump admitted: “You have to be a little bit nervous.”
Florida Senator Marco Rubio also praised the drive of rival Mr Cruz, who he has repeatedly clashed with on a range of issues, saying he “has a very strong ground game”.
Democratic hopeful Hillary Clinton praised her campaign staff and said that rival Senator Bernie Sanders has run the campaign he wants to run, noting simply, “we have differences”.
