EXECUTIVE SUMMARY
CNN data analyst Harry Enten warns historical polling errors could hand the Senate and House back to Republicans in upcoming midterms.
Democrats who have been telling their constituents the party is on the verge of a big blue wave during next month’s midterm elections are very likely overselling the expected results.
That’s according to CNN’s data guru, Harry Enten.
Enten warned on Friday that even a relatively ordinary polling error could completely reshape battles for the House and Senate.
