Is this the end of the line for Santorum?

Republican favourite Mitt Romney scored a hatrick of primary wins last night, making the inevitable now seem even more inevitable.

Despite continually struggling to capture the imagination of the Republican base, Romney’s wins in Wisconsin, Maryland and the District of Columbia will only increase pressure on the other candidates to drop out of the race, and restore party unity.

However main rival Rick Santorum told supporters after the night’s events that:

We have now reached the point where it’s half time – half the delegates in this process have been selected. Who’s ready to charge out of the locker room in Pennsylvania for a strong second half?

While the race may only be at the half-way point, it now seems almost impossible for Santorum to pull off a comeback, with his challenge against Romney seemingly weakening rather than growing stronger. The key test will be Santorum’s home state of Pennsylvania which goes to the polls on 24 April.

If he fails to win, the race will likely be all but over.
