I checked the major Democratic rivals Twitter feeds this morning for signs of life after yesterday's primary in Pennsylvania.
From Hillary Clinton's Twitter account, about 10 p.m. Eastern on Tuesday:
"Thank you Pennsylvania!!"
And from Barack Obama's Twitter account, about noon on Tuesday:
"Traveling through PA today & asking folks to vote for change! If you are in PA & need polling location info visit http://pa.barackobama.com."
