“For 2018, the CBS News Battleground Tracker has gathered a panel of nearly 5,700 registered voters. Almost all of them live in the 50 to 60 districts that might switch from Republican to Democrat, or vice versa, in November — the only races that matter, when it comes to control of Congress.”
So if some other district, one that they’re not tracking, has an ‘unexpected upset’, they will once again be caught short.
How queer, why is the potential outcome even “news” for impartial journalists?
Both sides present their candidates and the public makes a decision to vote, or stay home, or ignore certain offices.
Until all of the votes are in, only someone trying to sway the outcome is interested in how close it is in the leadup to the election.
