Which did the Republicans do better in?

[win win]

House or senate? Which one was more surprising?

How Republicans do in Georgia affects the Senate answer. Traditionally R's do better in runoffs in Georgia, but the results this year demonstrated it has moved squarely into purple territory. It's worth noting overall, there was only one split ticket thus far with the presidential race (Maine, which benefited Republicans).

I would say though the House due to expectations. R's are going to end up around 210 seats, give or take a few. FL-27 was rated 'Likely D' by pretty much everyone, TX-23 was an R-hold by 3 points which was heavily expected to go to Democrats (thanks, Latinos!). Also, Democrats did WORSE in almost every district they just fell short in 2018 in Texas. They're also going to lose at least 1 California seat, and they're going to hold some Dem incumbents to some embarrassing single-digit margins like Tim Ryan, Susan Wild, Cheri Bustos, Ron Kind, Jared Golden, etc. that were supposed to be Safe or Likely.

[I need an explanation]

The house. Nothing in the senate was really surprising.
