All eyes are on Senator Krysten Sinema (AZ-D) as America awaits to hear the fate of the disastrous spending and tax bill agreed to by Senator Joe Manchin (WV-D) and Senate Majority Leader Chuck Schumer.

Last week, Manchin pulled a 180 on America and decided to back Biden’s new “Inflation Reduction Bill” which many claims is a retry of the failed Build Back Better deal that Manchin and Sinema shot down in December of 2021.

The bill is set to tax nearly every income bracket despite Joe Biden’s several promises that it would only tax those making over $400,000. Manchin who previously said the bill wouldn’t increase inflation further, which is why he shot down Build Back Better in the first place, just admitted that it was a mistake to suggest that it wouldn’t and that he now believes it will have a further impact on inflation in the United States.

Manchin, D-W.Va., said he plans to talk with Sinema, D-Ariz., on the Senate Monday about the bill. But her office says it may take a little longer for the senator to decide how she will vote.

“Sen. Sinema does not have comment as she’s reviewing the bill text and will need to see what comes out of the parliamentarian process,” a spokesperson for the senator told Fox News Digital Monday.

With a 50-50 Senate, and Republicans standing firm against the Manchin-Schumer bill, every vote will count for Schumer, D-N.Y., which means Sinema could single-handedly kill the bill from ever seeing the light of day.

That means Washington is anxiously waiting to see where she comes down on what may be the Democrats’ last and best chance to pass the social spending bill before the midterms. Adding to the drama, Sinema’s announcement may not come until later in the week, due to the nature of the parliamentarian process her spokesperson referred to.

According to a Fox News article, Senate Parliamentarian Elizabeth MacDonough this week will hear arguments from Republicans and Democrats over whether certain parts of the bill comport with the Byrd Rule. That process is called the Byrd Bath.

Democrats are attempting to use the Byrd Bath rule to get around the 60-vote filibuster. The Byrd rule is enforced when a Senator raises a point of order while considering a reconciliation bill or conference report. If the point of order is sustained, the offending title, provision, or amendment is deemed stricken unless its proponent can muster a 3/5 (60) Senate majority vote to waive the rule.

McDonough will rule on which provisions don’t fit that definition, making them what the rule calls “extraneous matter.” Technically, the Senate could overrule the parliamentarian, but top lawmakers haven’t indicated they plan to do so.

With a bill hundreds of pages long it could be several days before Sinema announces her final position, which could either shatter Democrats’ hopes of a significant legislative victory or power them to what could be their biggest, yet disastrous for America, win yet.
