[politics] OBAMA win & newspaper front pages

November 6th, 2008

On November 4th, 2008, Barack Obama was elected as the 44th president of the United States.

It was grand, historic night  – not just for us in US, but all over the World.

I wanted to grab a newspaper – with a front page image – on Nov 05 (the day after) as a souveneir of this day.  But they were sold out every where I went !  Finally, I managed to grab a ‘customer copy’ of San Jose Mercury News from  a Cafe by 8pm.  I am really thankful to the Cafe owner who just gave it to me FREE !!

Here is the front page image from Mercury News

SJ Mercury News

And from San Francisco Chronicle:
