Washington | Americans are waking to another two years of gridlock and bitter partisan warfare under an emboldened Donald Trump after Democrats won control of the House of Representatives but fell short of a "blue wave" landslide that would have represented a comprehensive repudiation of the President.

After a rancorous three-month campaign, voters delivered their verdict on Mr Trump's two years of political polarisation, putting Democrats on track to gain as many as 35 seats, or 12 more than needed for the majority in the House.
