LGB Voters Provided Obama's Mandate

From Professor Ken Sherrill of Hunter College Political Science Department:

Obama has won with 52% of the vote.

LGB voters accounted for 4% of the voters in the exit polls.

According to the exit polls, 70% of LGB voters voted for Obama.

70% of 4% is 2.8%.

Subtract 2.8% from 52% and you get........

No mandate.
