Potential Pennsylvania Senate candidate and talk show host Chris Matthews gets mentioned in two of Politico's Top Ten Media Blunders of 2008.

Leading the list was Matthews and his fellow pundits' premature dismissal of Hillary Clinton in the New Hampshire primary.

Writes Michael Calderone: New Hampshire primaryPundits predicted a campaign-ending, double-digit loss long before the polls closed, and some networks, perhaps disbelieving the results, didn't call the election until after Obama had already conceded. "I will never underestimate Hillary Clinton again," Chris Matthews said on MSNBC's Hardball.

Coming in at Number Three was MSNBC's decision to pair Matthews with Keith Olbermann on Election Night.

Writes Calderone: Having MSNBC stars Chris Matthews and Keith Olbermann co-anchor Election Night and convention coverage drew the public ire of conservatives (and many Clinton supporters), and internally network journalists grumbled that the pair tarnished NBC's established journalism brand.

Meanwhile, the buzz around the Web is that Matthews may make public his decision on whether he will challenge Sen. Arlen Specter in 2010 sometime before Inauguration Day.
