A couple things to keep in mind.
Putting freshman Members up as Committee Chairs (as was being demanded by the unwashed mob) is an absurd path to political suicide. This year, even allowing them to speak appears to be fraught with hazard.
On the other hand, the Dems do not follow the same rules the GOP follows when in power. The Dems run purely on seniority when it comes to committee Chairs or Ranking Member. This is sticking in the craws of younger members and their fan base.
The GOP at least has a rotation system that opens up committee slots for younger (but not freshmen).
The big problem is that, so far, the above cartoon is not even close to accurate. From what we have seen so far, 3 freshman members have been driving the entire party since November. With not apparent end in sight. If Pelosi cannot get her House in order there will be serious consequences at the polls in 2020. I am willing to venture that a large majority of Americans are not pleased with the public furor surrounding the 3 new girls o the block.
