And how will the up and down of prices and the economy affect the midterm elections, now less than 100 days away? Oil prices will for sure come into play. This week, crude oil prices have remained above $80 a barrel, which could translate into higher prices for Americans as they take to the skies. According to TheStreet, American Airlines said its fuel costs increased by more than $2.2 billion during the second quarter, an 83% increase. That means oil prices, airfare, inflation and the broader economy could all become major issues as voters head into the midterm elections.
