But that's true for literally every issue. Rural voters are equally less aware of city issues. White voters are less aware of issues faced specifically by minorities. Men are less aware of female health issues. Skewing votes in favour of one group or another is never going to fix that.

The only way to fix it is to ensure that all opinions are represented. A multi-party system with proportional representation will accomplish that much better than a skewed and polarised two-party system.
