The left is celebrating Conor Lamb, but are they popping the Champagne too early?

Democrats are rightly excited about Conor Lamb’s win in the Pennsylvania special election. But, they need to consider a few things before the fall midterms. A roundup of editorials Friday takes a look at the issue.

Opinions from the left:

1. A Conor Lamb victory in Pennsylvania could also spell trouble for Nancy Pelosi

From The Washington Post: How sure a bet is Nancy Pelosi for speaker even if the Democrats take back the House?

2. Dems Should Be Careful About Their Big Win in Trump Country

From Time: What came together in Pennsylvania isn’t necessarily what will happen around the country this fall.

3. Settle down, Democrats

From The Week: There are reasons not to get too excited about the special election in Pennsylvania.
