At the same time, the former Secretary of State appeared to have deliberately avoided attacking or even mentioning Donald Trump – the Republican presidential frontrunner – in the debate in Iowa last night.

While Clinton's other two Democratic presidential rivals - Bernie Sanders and Martin O'Malley - did attack Trump, she appeared to have learnt lessons from the last debate in which she openly criticised Trump, following which she was strongly attacked by the real estate tycoon and his supporters.

Clinton on her part maintained her cool and preferred not to attack or even mention Trump during the entire debate.

Even when she had an opportunity, she only mentioned the Republican candidates.

Instead, Clinton appeared to have embraced the policies of President Barack Obama in whose first term she served as the Secretary of State.
