By piggybacking the [Government Takeover of the Health Care System] legislation onto a budget bill, Democrats would be able to advance the bill with a simple majority of just 51 votes, averting a Republican filibuster in the Senate.
[. . .]they can use the aggressive and contentious tactic, known as reconciliation, to pass a far-reaching health care bill in the Senate without having to face the GOP. Democrats lost their ability to block filibusters when Massachusetts Republican Scott Brown won a Senate seat last month.
Reconciliation is the process of passing a bill in the Senate with a simple majority, 51 votes. The rules were changed a few years ago when the Democrats wanted a super majority (60 votes) in order to approve nominations for Federal Judges. For some reason, Democrats didn't want someone named Miguel Estrada nominated for a position on a circuit court. Seemed kind of racist to me at the time.
The scariest aspect of reconciliation? It could be all up to Joe Biden.
