The talking heads on MSNBC are bringing up a good point – by referencing McCain’s temperment, Barack Obama has indicated he will not hold back if McCain continues his patriotism attacks.

It’s well known that many Senators who have served with John McCain, including Republicans, are terrified at the thought of John McCain as president. The concerns rest with whether he is too unstable or volatile to be commander-in-chief.

For anyone paying attention, it should not be a surprise that Obama went right after McCain tonight. Expect this to continue.

With one word, Barack Obama summed up the appropriate response to the last eight years under George W. Bush.

It was an historic speech. Some have quibbled that the Democrats were not tough enough on Bush, Cheney and McCain during this convention. Barack Obama took it upon himself to deliver the toughest punch.
