(CNN) - Florida Rep. Connie Mack won Tuesday's Republican primary in Florida over other Republicans seeking to challenge Democratic Sen. Bill Nelson.
Mack's main opponents–former Rep. Dave Weldon and retired Army Col. Mike McCalister–conceded.
Phoenix (CNN) – On primary day in Arizona, Republican Senator John McCain seemed a man of few words considering his front runner status. Joined by his wife, Cindy, who was wearing a leopard print suit, McCain voted at Phoenix's Madison Camelview Elementary School shortly after 9 a.m. MST. He chatted briefly with school kids and their parents then gave 21 seconds of remarks to the gathered press before refusing to take questions.
The candidate, seeking a 5th term as a U.S. Senator from Arizona, told gathered media: "We're looking forward to a good turnout today and there's already been a lot of early voting. We're confident we're going to win but obviously it isn't over till it's over."
McCain joked about the weather, and promised to "take nothing for granted." As he started to walk away, CNN asked him to respond to his opponent's charge that he'll move to the left if re-elected. The candidate smiled and kept on walking.
(CNN) – As voters in five states go to the polls on Tuesday, big-dollar challenges to veteran politicians dominate the top races.
The big storylines: Two billionaire political newcomers spent millions of their own money to try to pull upsets in Florida, Arizona Sen. John McCain is expected to fend off the biggest Republican primary challenge of his Senate career and a little-known Tea Party candidate is taking on an incumbent senator in Alaska.
Voters will also pick the Democratic gubernatorial nominee in a wide-open Vermont race, and decide the runoff winners in two Oklahoma Republican primaries.
(CNN) - Voters in Washington state and Wyoming hold primaries Tuesday, with the Senate contest in Washington and a battle for the open Wyoming governor's seat the most closely watched races of the day.
In Washington, Democratic Sen. Patty Murray and Republican candidate Dino Rossi are expected to emerge from a crowded primary field, setting up a November showdown. Under the state's system, the two candidates who receive the most votes regardless of party affiliation move on to the general election. Voting has been underway for two weeks, with Washington primarily a mail-in ballot state.
In many ways, Murray and Rossi have already begun their general election campaigns, focusing their attacks on each other. Polls show a close race in the fall if they both advance.
(CNN) - Tuesday's primary contests will put the nation's anti-Washington mood to the test as voters choose between incumbents and anti-establishment candidates.
The races come in the wake of some tough blows to sitting lawmakers: Sen. Bob Bennett, a three-term senator, failed to advance at the Utah GOP convention, and Rep. Alan Mollohan didn't win over fellow Democrats in last week's West Virginia primary.
Leaders of both parties agree - it's a tough year for experienced politicians.
"There is no question. There is, at this moment, an anti-incumbent mood," said House Speaker Nancy Pelosi, D-California. And House Minority Leader John Boehner, R-Ohio, warned, "It's 'politicians beware.' "
