On election night, Donald Trump repeated the phrase: “Promises made, promises kept.”

Now Republicans have officially taken control of Congress, and it’s much easier to keep his “promises.”

In Washington political parlance, the situation in which the president’s party also controls both chambers of Congress (the House of Representatives and the Senate) is called the “governing triumvirate.”

That control is now in the hands of Donald Trump’s Republican Party.

One-party control was once common, but has become rarer and shorter in recent years. More often than not, the party in power loses seats when congressional midterm elections are held approximately two years later.

Both Trump and Joe Biden enjoyed the trifecta in their first two years in the White House, but they also found that having such control was no guarantee that a president could get what they wanted.

Trump passed a signature tax bill in his first two years that reduced corporate taxes from 35% to 21% and cut some taxes on individuals.

But he has struggled with other causes as some members of his own party resisted his surprise rise in 2016.

His plan to repeal the Affordable Care Act (known as Obamacare) failed because John McCain, a senator from his own party, refused to vote for the legislation. He also failed to pass an infrastructure bill as promised.

In his first two years when Democrats controlled the House and Senate, Biden managed to pass the American Rescue Plan, the Investment and Jobs Act, and the Chips and Science Act. But over the objection of one of his own senators, he too was forced to significantly scale back his sending and investment plans – billed as the Build Back Better package.

The biggest obstacle to full control for both parties is that Senate bills require a three-fifths majority, or 60 votes, to bypass the filibuster that allows senators to delay legislation by keeping debate open-ended. This means that if a party has a simple majority in the Senate, it must cross the aisle to pass the bill.

Even with a healthy majority in the Senate this time, Trump won’t have the magic 60 seats that would allow him to overcome opposition efforts to delay the legislation.

And on Wednesday, Senate Republicans chose John Thune as majority leader over Rick Scott of Florida, the clear favorite of the Trump wing; it’s a sign that some lawmakers may be reasserting their independence (Trump has not formally endorsed Scott).

However, a triad, if managed wisely, opens up the possibility of major legislative initiatives.

Trump’s power advantage could be key to delivering on his big promises, such as the largest immigrant deportation in history, eliminating tariffs on foreign imports and rolling back environmental protections.

Using legislation to achieve these ends will make it much more difficult to overturn such plans in the courts; This was something that plagued Donald Trump during his first term, when he made extensive use of executive orders that were regularly and often successfully challenged.

The judicial environment has also changed in favor of Trump.

The signature achievement of his first term was the installation of three conservatives on the Supreme Court; This would likely solidify a two-thirds majority for decades to come.

He also appointed more than four dozen judges to federal appeals courts, shifting many circuits to a more conservative bent.

The majority that Republicans have in the Senate also provides a significant advantage.

Trump will be able to more easily get his candidates approved for administration positions; He had difficulty with this in 2017, when internal resistance against him in the Republican Party was still significant.

All of this indicates that the next two years will be busy and possibly turbulent. However, as recent history shows, these trilogies do not last that long. The new management will want to take a step.
