About to fall asleep at the computer. Too bad I have two church meetings tonight.

Here are some remains of a busy day:

* Vermont NPR affiliate is reporting that Bernie Sanders will announce a presidential bid on Thursday.

* ThinkProgress‘ Bryce Covert provides a backgrounder on Baltimore’s economic distress.

* New PPP poll of Iowa Republicans again shows Christie and Bush with worst favorable/unfavorable ratios in the field.

* At Ten Miles Square, Julia Azari argues that most of the sins people accuse political parties of are actually attributable to “reforms” aimed at curbing parties.

* At College Guide, Jill Barshay discusses new research showing that while online courses seem to work well for students at four-year colleges, they don’t work at all for students in community colleges.

And in sorta non-political news:

* Jobs most in demand at the moment also have some of the lowest pay and benefits.

That’s in for Tuesday. We’ll close with a rather anachronistic take on the “Streets of Baltimore,” as performed by Gram Parsons and Emmylou Harris.
