It is. Just one you are not willing to accept. But that's okay.
The reason it is not an answer is because it doesn't address the question. Telling me "because birds have feathers" doesn't answer when I say "when the Senate changes hands, and the filibuster that currently impedes the Democrats is no longer available to help the Democrats".
Everybody else seems to comprehend it. I guess you're just special. I'll repeat - because Republicans are so hell bent on gerrymandering and voter disenfranchisement, the next time they win the senate the idea of a filibuster will be irrelevant.
Same answer, reworded a little differently for you to understand.
