People trust the ABC more than any other news source and would like to see it given more money and protected from political interference, research shows.

The poll, conducted by Research Now for think tank the Australia Institute, found voters trusted and were supportive of the national broadcaster regardless of their political leanings.

Seventy-six per cent of the 1443 people surveyed on behalf of the left-leaning think tank agreed that the ABC should be protected from political interference.

Support was strong among voters regardless of party allegiances with 76 per cent of Coalition voters in favour of the ABC being protected from political interference, 74 per cent of Labor voters and 87 per cent of Greens voters.
