They are just extraordinarily playing within the rules. After all, precedent was set in 1968 with the (R) Filibuster of AbeFortis, an unEthical nominee for Chief Justice of the Supreme Court.
Likewise, Frist is also just extraordinarily playing within the rules. After all, precedent was set in 1979 when on 4 occasions, the (D) Senate Majority leader, Robert Byrd, executed a planned chair ruling that legally endRan and Busted a (D) legislative filibuster.
Byrd's precedent setting 1979 actions will be especially usefull to Frist if the (D)s counterattack and "bring the Senate to a screeching halt."
Byrd's precedent setting 1979 actions were designed to counter that exact strategy on specific legislation.
Oh, I'm not using the blame game. Or, not trying to. What I AM urging is effective leadership on the GOP side to bring these judges to a vote. Just a bit of research exposes the Fortes elevation to Chief Justice as not the same thing that's going on now.
Both sides may have used the filibuster in the past to varying degrees, but there's not much argument that the Democrats are abusing their limited powers and stretching the history of filibusters to justify their position.
