To some extent I agree, but most politicians are essentially unknown to the wider public so I'm not sure it's that applicable.
It's only really the cabinet/shadow or the top few spots for Lib Dem, Green etc who are put under any real public scrutiny, and even then there are swathes of the public who won't even know who, for example Jenrick or Yvette Cooper are. Most of the near 700 or so MPs could walk up and down any street in the country and they'd never get recognised.
That said Jess Phillips has obviously had dogs abuse for basically being a woman from very normal beginnings in the North so I suppose there is that.
