Depending on where you are in the world, tomorrow is either RBA interest rate day, Melbourne Cup day or, if you're in America, election day.

While the US midterm elections don't attract as much coverage as the Presidential election, the outcome is still consequential to the investing landscape.

Tomorrow's election will determine which party controls Congress. This will significantly affect legislation and executive action and will shape the direction of congressional hearings and investigations. Some sectors and ASX shares will benefit, while others will be disadvantaged.

The Republican Party currently controls both chambers of Congress.

The Democrats have been expected to take back control of the House for quite some time.

Earlier this year, the prospects of them also taking back the Senate were slim. However, in recent months, Democrats' odds of taking back both chambers have risen.

With several key Senate races now rated a toss-up, Democrats have a slight edge.

Most notably, Texas could be on the cusp of electing its first Democratic Senator in more than 30 years. In recent weeks, Kansas, which Trump won by double digits in 2024 and hasn't elected a Democratic senator since 1932, has also been moved to a toss-up.

Investors have been quietly shifting their expectations from a split Congress to a Democratic-controlled Congress.

Should this eventuate, the balance of power in Washington would be divided for the next two years. A Democratic Congress would serve as a check and balance on Donald Trump's agenda.

How could this change the investing landscape?

Let's consider three types of ASX shares that could swing the hardest based on the outcome.
