Ed Markey's progressive credentials outweigh age concerns

At a glance, Sen. Ed Markey (D-MA) is exactly the sort of Democrat who should be at risk of succumbing to an anti-establishment wave that has taken down a dozen incumbents this cycle, many of them older.

Markey is 80 years old and has been in Congress longer than his opponent, Rep. Seth Moulton (D-MA), has been alive. And he’s running in an environment that has at times favored younger upstarts — candidates who’ve been able to separate themselves from the damaged Democratic Party brand.
