You're not wrong .. when Al Gore contested the election, election boards, judges, & political pundits in Main Stream Media ALL backed the recount efforts -- because it's a right for a Candidate to contest the results & they stressed the importance of secure accurate elections.
However when Trump tried to contest the election... Election boards went silent, judges refused to hear cases, and political pundits of MSM all rejected the idea of a contested election & made sure to spell out that the election was the most safe and secure election that ever occurred.
So you're right - one situation was a Candidate contesting results & everyone jumping on board to contest the election via recount & the other one was a Candidate not getting the chance to contest elections.
