Pennsylvania democrats vote today in the presidential primary, a very important contest for Senators Clinton and Obama.  Be sure to watch The NewsHour with Jim Lehrer at 7pm for the latest information just before the polls close at 8pm in the Keystone state.  Charlie Rose will also provide live coverage of the primary and analysis of the results.  You'll see that at midnight right here on WTCI.  And of course, you can keep track of what's going on anytime right here on the Vote 2008 section of wtciTV.org.
