From a reader:

Jonah,
At the conclusion of Bill Clinton’s trial in the
Senate, Arlen Specter’s Scottish vote gave Ted Kennedy
the ability to crow that supporters of removal were
not even able to muster a majority (the final vote was
50-50). Kennedy used that fact to argue, with some
effectiveness, that Republicans had wasted the
country’s time.
I vowed that day that if I ever had an opportunity to
vote against Arlen Specter in a primary, I would walk
over broken glass to do it. I am one happy
Pennsylvania Republican this week. My fingers are
crossed.
