Rep. Connie Mack IV, who had broad support from just about every swath of the Republican Party, easily picked up the GOP nomination for Senate to take on Sen. Bill Nelson (D) in November.

Mack defeated long-shot candidates former Rep. Dave Weldon, retired Army Col. Mike McCalister and activist Marielena Stuart in primary. With 42.7 percent of precincts reporting, Mack had 58.5 percent of ballots cast, according to the Associated Press.

Nelson also easily dispatched a nonserious opponent. The two-term Senator took 79.3 percent of the vote, with 43.1 percent reporting, per AP results.

Mack is seen in both Democratic and Republican circles as a particularly weak candidate. The race in November favors Nelson.

Roll Call rates the Senate race as Leans Democratic. Nelson is widely expected to outperform President Barack Obama regardless of whether he wins the battleground state.
