100 days: Dems have midterm edge, but it's not historic

But their edge is not as significant as the winning party’s advantage in the last two major wave elections, in 2010 and 2006. Eight years ago, Republicans held a 15-point enthusiasm edge, and they picked up 63 Democratic-held seats in former President Obama’s first midterm election.

Four years before that, Democrats had a 32-point enthusiasm gap, and the party picked up 30 seats.

“Democrats are angry, and that’s not changing in the next 100 days,” said Ron Klain, a Democratic strategist and former chief of staff to Vice Presidents Joe Biden and Al Gore. “The unknown is whether that anger turns into a huge turnout.”
