Once an incumbent survives a primary challenge, the odds of winning a general election are extremely high due to wide name recognition and the amount of funds accumulated.

Both the Republican party and outside groups spent large sums of money in a few "toss-up" races, only one of which featured a Republican incumbent: Senator Mitch McConnell from Kentucky, who had amassed a large war chest of his own. In contrast, Democrats were forced to defend across the country, resulting in less resources being available to each candidate. The result was the Republicans being elected to a majority to both houses of Congress.Learn more about Political Parties
