Easy Peasy. That is, unless some hinky irregularities happen during the election that could stall the certification, and I expect there to be some issues.

Looks like all hell is about to break out next week. Happy Holidays! Oh, shit. I mean, Merry Christmas!


TUESDAY, NOV. 28: Senate reconvenes after a week-long holiday break. Republicans could unveil their tax bill.

THURSDAY, NOV. 30: Possible, although far from certain, final Senate vote on tax bill.

FRIDAY, DEC. 8: Expiration date for funding needed to keep the U.S. government open. Congress has three choices: approve a massive bill for more than $1 trillion to keep the government operating through Sept. 30, 2018; pass a shorter extension of current funding to buy more time; or fail to pass anything and risk a partial government shutdown, stalling the tax effort.

U.S. Treasury hits its limit on borrowing, but takes steps to postpone any need for action by Congress, eliminating any need for a debt limit increase in an end-of-year catch-all bill.

TUESDAY, DEC. 12: Special U.S. Senate election in Alabama pits Republican Roy Moore, a conservative firebrand accused of sexual misconduct involving teen-age girls, against Democrat Doug Jones. The election could mean trouble for the tax overhaul effort. Moore, a critic of Senate Republican leader Mitch McConnell, could cause turmoil if elected. A win by Jones would shrink even more Republicans’ narrow margin of Senate control, which now stands at 52-48.

THURSDAY, DEC. 14: House’s last scheduled session of 2017.

FRIDAY, DEC. 15: Senate’s last scheduled session of 2017.

THURSDAY, DEC. 21: Seen by some as a possible date for swearing in a new Alabama senator, which would create new uncertainty for the Republican tax overhaul drive. But Alabama officials say the election results will not be certified until Dec. 26 at the earliest. With the Senate scheduled to be out that week, no new senator could be sworn in until January.

FRIDAY, DEC. 22: The last weekday before Christmas, and a potential deadline for sending tax legislation to Trump.
