Call her Sarah Pa-LIN ... because the former Vice-Presidential candidate is the new Knicks' sensation's biggest fan -- even showing off her brand new "LINSANITY" t-shirt on the streets of New York today.
According to Sarah, Jeremy Lin is everything America stands for -- calling him "an American story ... uplifting, positive ... he unifies our country!"
But when it came to deciding between Lin and Tim Tebow -- Sarah reverts to politician mode, telling us she can't decide between the two ... she loves them both. Lame.
