Voters in five US states go to the polls Saturday to make their choices for who should square off in November's presidential election, dpa reported. Both Democrats and Republicans vote in Kansas and Louisiana, while Republicans caucus in Kentucky and Maine, and Democrats hold similar meetings in Nebraska. Saturday's elections are the first polls since Super Tuesday, in which a dozen states made their choices and solidified the front-runner status of both Republican Donald Trump and Democrat Hillary Clinton. In the aftermath of Super Tuesday, the Republican establishment has been struggling to prevent the billionaire newcomer from seizing the conservative party's nomination for the fall elections. Nevertheless, Trump remains well ahead in polls for the Republican contests, though he has yet to amass enough delegates to put him entirely out of reach of his competitors. His remaining competition includes US senators Ted Cruz of Texas and Marco Rubio of Florida, and Ohio Governor John Kasich. In the Democratic races, former secretary of state Hillary Clinton leads voter surveys over Senator Bernie Sanders of Vermont.
