Romney, the clear front-runner, doesn't have the 1 144 delegates needed to win the Republican nomination, so he will still have to go through the motions of primary races because ex-House Speaker Newt Gingrich is insisting on staying in the race until the bitter end. When Santorum suspended his campaign on Wednesday, speculation about whether or not he would endorse his former arch nemesis began.

He even got a call from Romney himself asking for a meeting to chat about an endorsement. Since Santorum only suspended his campaign, he can keep the delegates he won in the 11 primary states and release them to any candidate he likes at the Republican convention in August. He may not have liked Romney for president, but Santorum has to realise that handing over his 285 delegates to anyone but Romney would be a waste.

The main focus of the Republican race now is who will be Romney's running mate. Many names have been bandied about, among them former presidential hopeful, Herman Cain. He is ready to ditch Gingrich and throw his rather minuscule weight behind Romney - all probably in the hope of becoming Romney's vice-president. The most popular choice is Marco Rubio, a Latino junior senator from Florida, an important swing state.

 He would help Romney get the coveted Hispanic vote. Rubio is also the guy who co-sponsored the Child Interstate Abortion Notification Act, the law which would make it a crime for anyone other than a parent to accompany a young woman to get an abortion in a different state.

 He also voted for Florida's controversial Stand Your Ground law, currently under the spotlight following the shooting to death of unarmed teenager Trayvon Martin by neighbourhood watchman George Zimmerman. My personal favourite has got to be Sarah Palin's pick, Allen West, an African-American Republican House representative from Florida. A video that's doing the rounds shows West saying that he's heard that 78 to 81 House Democrats are Communist Party members.
