New Yorkers vote as Democrats weigh competing visions in era of Trump

Democratic primary elections to test strength of party's left flank as old guard faces string of challenges

New Yorkers were voting on Tuesday in a slate of Democratic primaries poised to reveal the strength of the party's left flank and shape the battle for control of the US House of Representatives in November.

Voters in Maryland and Utah will also nominate congressional candidates on Tuesday, while South Carolina holds a series of runoff elections for candidates who did not receive a majority of the vote earlier this month.
