I'm positive if the Democrats eliminate the filibuster for another short term gain, it too will come back to bite them even harder. But that's their call, not mine.
Why should it concern you that Democrats might get bitten in the butt?
You aren't one of them and their agenda is not your agenda.
The filibuster itself seems to have worked more to divide the parties than it has to unite them. In a different day and time it might serve a purpose, today it's just a spanner in the works and it prevents either party from getting anything done. To support the filibuster you support the gridlock.
All is not fair in war or love. But in politics it is.
Trump proved that.
