Why are Pataki, Graham and Santorum still in the race?

I'm sure that millions of voters are wondering the same thing. It's highly unusual for candidates who poll that exceedingly low to stay in a presidential primary race for so long.

The only answer is, they're employees of the GOP establishment, who've put them there to act as pawns in a chess game. They'll stay in the race just as long as they're being paid to do so.

They stay in the race as long as the contributions are greater than the low rent expenses, thus building up the total.

Once the expense is greater than the take, they bow out.
