Is it Obama vs Romney already?

While the Republican primaries don’t end until June, it looks like Republican front runner Mitt Romney and US President Barack Obama have their sights set on a head-to-head race for the presidency. Romney is still campaigning for a Republican nomination with primaries still to come, but his focus seems to have moved on to his future rival. Recently, Romney took a jab at President Obama saying Obama’s version of a perfect world is one with “a big spending environment”. The Obama camp, on the other hand, has put out advertisements directly naming Romney as a backer of “Big Oil” companies despite steep prices of gasoline.
