Matheson won the race for seat in Utah's 2nd Congressional district against Republican challenger Mia Love. The race received national attention not only because it was close, but also because Love was the first Haitian-American Mormon woman to run for Congress.
McIntyre claimed victory in the race against GOP challenger David Rouzer on Saturday, but since the margin of difference in the votes is less than 1%, Rouzer has requested a recount under North Carolina election law.
"[Rep. Mary] Bono Mack didn't go back to the district a lot; [Rep. Allen] West is a controversial character," Rothenberg continued pointing to two key Democratic upsets.
Bono Mack conceded defeat to her Democratic challenger in the race for the seat in California's 45th Congressional district. West, a tea party favorite, conceded defeat to his Republican-turned-Democrat challenger Patrick Murphy Tuesday morning after weeks of accusations, recounts and legal wrangling.
What does this mean for the 113th Congress? More polarization, some say.
"There's no doubt that this is the most polarized house in American history," Wasserman said. "Republicans have redrawn themselves into more security but they've also redrawn themselves into an alternate universe than the rest of the country," he said.
Wasserman points to the 88% white male make up of the House Republican party, creating a different incentive system for them.
"Republicans don't have to worry about the next election but Republicans have to worry about the next primary," Wasserman said. Since early 2000's, conservative Republican challengers have been running to the right of GOP incumbents, he said.
If the midterm electorate resembles, as Rothenberg anticipates, the 2010 electorate that came out strong for tea party Republicans, Democrats could find themselves playing mostly defense on the GOP's home field.
"The midterm electorate will be whiter than the last election," Rothenberg said, noting that the first constituencies to drop off in the midterm election are youth and Hispanic voters -- two voting blocs that helped Democrats win in 2012.
