All seven incumbents who ran for re-election, none of whom faced viable challengers, were returned to Congress. None received less than 60% of the vote, and one received over 80%. In addition, the two seats vacated by retiring Republicans were both reclaimed by Republicans despite Democratic hopes to gain at least one seat in the vulnerable 8th district.
