As POTUS tweeted-
Tremendous success tonight. Thank you to all!
Q-
Senate means everything.
Think Judges (SC) & Cabinet
Winning! Why?
Length of term- House 2 years. All 435 seats are up for reelection every two years.
Length of term - Senate 6 years. Here there is a continuous body idea. Only 1/3 of the senate seats are elected every two years. So only 34 or 33 senators are up for election at one time.
