A filibuster is possible because the GOP has taken steps to protect its existence. You aren't aware of this, because if you were, you wouldn't have written your post.
"It would seem there isn’t much appetite for ditching the filibuster, especially in a Senate run by newly elected Majority Leader John Thune, R-S.D., a longtime protege of Senate Republican Leader and 60-vote threshold defender Mitch McConnell. Fellow McConnell stooge Texas Sen. John Cornyn recently told NBC News that there’s “unanimity” among Senate Republicans on preserving the filibuster — even if President-elect Trump again calls for senators to dump it. "
That paragraph came from this article:

--- and while it's an article about different legislation, the paragraph on filibusters is relevant to the current situation.
The GOP *WANTS* sixty votes to pass law. They could get rid of filibusters but do not want to.
Spend more time with your hydrangeas. Maybe self-identifying as a gardener would better suit you.
