On November 6th,  although Trump is expected to win the US presidential election, he may still need several days or weeks to know whether he has strong allies in the House of Representatives, partly because states with longer vote counting times, such as California and Arizona, have fierce competition. For months, neither party has had a clear advantage. In a series of fierce House of Representatives elections early Wednesday local time, the results were still inconclusive. The Democratic Party invested heavily in trying to regain control of blue state seats and saw it as a key path to regaining a majority in the House of Representatives.

Since the Senate is in the hands of the Republicans, if the House Republicans win, Trump may get the coveted "triple victory," paving the way for Republican legislative priorities such as tax cuts. But if the Democrats successfully reverse the Senate, a divided Congress could mean that Trump will face the partisan struggle over spending and debt limits that has plagued lawmakers for the past two years.
