Here's who Wall Street thinks will win the midterm elections

Wall Street analysts are betting that Tuesday's midterm elections will flip control of Congress, with potentially significant implications for the U.S. economy.

History backs them up: The president's party has lost between 25 and 30 House seats in nearly every modern midterm election. But this year, the economy is playing an outsized role. A recent Gallup poll found that the portion of registered voters calling the economy "extremely important" in who they support at the ballot box is at its second-highest level in two decades.

Muddying the picture this year is that the economy is sending mixed signals. A historically strong job market and high rates of Americans starting businesses coexist with the highest inflation since the early 1980s and soaring energy costs.
