Dear Senator Santorum,
Congratulations on running a fine campaign, you did very well and better than most would have thought, you fought the good fight, however now it is time to give it up you cannot win the nomination and by continuing to stay in the race you may weaken the republican nominee Mitt Romney.
You had a good run and should be proud and who knows maybe in four years you can try again but the race is over please get out and get behind the nominee.
