The new 18th District is centered in Martin and St. Lucie Counties north of West Palm Beach, and it is considerably more Democratic than Rooney's current constituency. The voters that elected Rooney to each of his two terms gave McCain 51 percent of their presidential votes in 2008; the new district into which Rooney's home was drawn went for President Obama at a 51 percent clip. Though the new 18th leaned Democratic in 2008, Obama's marginal victory there is nothing compared to the disastrous situation West found himself in when the new lines for his 22nd District were released. West's seat also leaned Democratic, going 52 percent for Obama in 2008 and 53 percent for John Kerry in the 2004 presidential race. But the new 22nd District -- again, rendered more compact by legislators keeping the Fair Districts law in mind -- went almost 57 percent for Obama. That leaves Hasner, the former state House majority leader and underdog Senate candidate who has failed to gain major traction in the polls and has struggled to raise money, as good a GOP fit as there is for the 22nd District. A source familiar with Hasner's plans said that he is likely to leave the Senate race to run for West's old seat, and he will likely come to a final decision in the next 24 hours. As the Miami Herald, which first reported that Hasner would likely switch races notes, West's district is similar in makeup to Hasner's old state House district.
