Earlier this week, Donald Trump was again highly optimistic about the GOP's prospects
in the midterms, telling reporters that the main base of the Democrats has shifted so far left that the U.S. would end up like Venezuela. The president said he expects a lot of Democrat voters to support Republican candidates in early November. Despite Trump's optimism, history is against his party. This has been the case for every sitting-president's party during the midterms since the Roosevelt era and since 1946, the party controlling the White House has lost 25 House seats on average in the midterms.
Two months before the 2018 midterms, Donald Trump has an approval rating of 40 percent. According to Gallup's polling history
, presidents with an approval rating below 50 percent have seen their party lose 37 House seats on average while presidents with a 50 percent or higher approval rating have lost 14 on average. Only two U.S. presidents have seen their party gain House seats according to the American Presidency Project
- Bill Clinton in 1998 and George W. Bush in 2002.
There are many reasons for the traditional poor performance from the president's party in the midterms and it doesn't always involve performance or legislative decisions. Lack of interest certainly plays a role given that supporters of the president's party are usually satisfied that their favored candidate is in the White House. Given that, they tend to turn out in lower numbers while supporters of the opposition are more energetic and motivated to head out and vote. The trend shows why the president's first 100 days is vital when it comes to pushing key legislation through. After the first midterm, the political landscape can change completely and that makes the pursuit of major legislation
difficult and in many cases impossible.
