Unlike the 2008 presidential election when candidates announced early and often, this time around candidates are taking their time throwing their hats into the race. Let's take a look at where things stand with potential candidates:
There's just one this time around -- President Obama. He formally announced in April that he is running for reelection. Obama hopes to raise a stunning $1 billion for his campaign.

In January, the former CEO of Godfather's Pizza announced an exploratory committee for a potential run. That is the final step before a formal announcement. Cain, who is also a talk show host, is considered a long shot for the nomination.
Pawlenty announced his exploratory committee in March. Pawlenty is the former governor of Minnesota and is seen as a rising star in the Republican party.
Roemer also started his committee in March. Roemer was governor of Louisiana from 1988-1992, elected as a Democrat before switching parties. Before that he was a congressman, serving four terms.
Romney formed his committee in April. Romney was an also-ran for the 2008 nomination, when he was famously unpopular with his fellow GOP candidates, and not too popular with voters, as it turned out.

Palin's star seems to have dimmed, but never count out the 2008 GOP Vice Presidential candidate and former half-term governor of Alaska. She remains a force, and would shake up the race if she decides to enter.
