'Hamas loves Obama' - Now why would that be the case?

Fox News report that:

'"Abu Hussain! Palestine loves you!!!"
This slogan, in English, appears on a poster and other products produced by the Palestinian Hamas movement and put on sale in Gaza. Yesterday, it adorned the front pages of several leading Arab dailies.
The "Abu Hussain" is President Obama. The poster pictures him wearing the signature Arab headgear, the kaffiyeh.
That the most radical Palestinian faction has declared its love for the president may be bad news for the stalled Middle East peace talks, which Obama has promised to help restart before the end of the year.'

Now why would Hamas so love Barack Hussein Obama?
