TAMPA, Fla. (AP) - Mutual admiration was the rule for Democratic Sen. Bill Nelson's listening session at the University of South Florida.
School provost Ralph Wilcox introduced the two-term senator as a "steadfast advocate for all Floridians." Nelson, best known for flying the space shuttle Columbia in January 1986, flattered the more than two dozen students present, saying they had a keen sense about people running for elected office. "You guys can usually smell out folks. You can spot a phony," he said.
Nelson collected their personal stories about the unbearable weight of student loans for a Senate speech days later on the need to keep the interest rate low. At the conclusion of the hour-plus session, he posed for photos with students.
Don't go looking for compliments and congeniality in the Republican primary to decide Nelson's election-year challenger. It's one of the meanest races in the country.
George LeMieux calls rival Connie Mack a congressional no-show, claiming that the four-term House member spends more time in California with his wife, Rep. Mary Bono Mack, than either in Florida or on Capitol Hill. A devastating web video from LeMieux portrays Mack as Hollywood bad boy Charlie Sheen, highlighting years-old bar fights and Mack's previous experience as an events coordinator for Hooters.
Privately, top Republicans in the state bemoan their choices and the GOP candidates' anemic fundraising.
It wasn't supposed to be like this in Florida or Pennsylvania or Michigan, three presidential battleground states. Republicans romped in all three in 2010, grabbing governorships, seizing majority control of state legislatures, and winning House and Senate seats. The three Democratic senators facing re-election in 2012 _ Nelson, Bob Casey of Pennsylvania and Debbie Stabenow of Michigan _ were certain to face top GOP recruits and strong political headwinds.
Now, roughly five months to Election Day, the three states look like missed opportunities for the GOP.
In Pennsylvania, Republican Gov. Tom Corbett's choice to challenge Casey finished an embarrassing third in the April primary. The GOP nominee is Tom Smith, who made a fortune in the coal mining business but lacks the name recognition of Casey, the son of a popular former governor.
In Michigan, former Rep. Pete Hoekstra, who finished second in the 2010 GOP primary for governor, stumbled in January with a controversial ad in which a young Asian woman spoke in broken English about China taking U.S. jobs. He faces a challenge from Clark Durant, who has the support of top Republicans Spencer Abraham and Saul Anuzis in a likely five-man primary on Aug. 7. Abraham represented Michigan in the U.S. Senate until he was ousted by Stabenow in the 2000 election, while Anuzis is running for Republican National Committee chairman.
The GOP envisions a road to a Senate majority _ it needs a net gain of four seats to win control _ but at this stage, Pennsylvania, Michigan and Florida aren't prime real estate.
"The environment can change in pretty short order," Casey said in an interview, recalling his father's success in 1990 and President Bill Clinton's in 1992, followed by Republican wins in 1994 and 1998. "We don't know what 2012 will be. We don't know whether it will be a dramatic departure from 2010 or not."
Christopher Borick, assistant professor of political science at Muhlenberg College, describes Casey as the prohibitive favorite based on his solid approval ratings, crossover appeal with Republicans and independents and his willingness to challenge President Barack Obama on several issues, most notably the requirement _ later amended _ that religious schools and hospitals provide insurance for free birth control to their employees.
Votes in Pennsylvania for Romney and Casey "won't be uncommon," Borick said.
Casey has $5.3 million cash on hand to Smith's $2 million, though the senator said "it's always a struggle when you're running against someone who can take out a pen" and write a personal check. Stabenow, who recently completed work on a five-year farm bill as chairwoman of the Senate Agriculture Committee, has close to $7 million cash on hand, while Hoekstra and Durant have about $1.5 million apiece.
In Florida, Republicans describe Nelson as one of the luckiest politicians, with support they insist is a mile wide but only an inch deep. They point to his less-than-formidable opponents in past elections, former Rep. Bill McCollum and divisive 2000 recount figure Katherine Harris, whom he beat 60-38 percent in 2006.
Mack, in the first rush of fundraising, emerged with just $1.38 million cash on hand at the end of March, according to Federal Election Commission reports. LeMieux had $1.19 million. By comparison, Nelson reported $9.54 million cash on hand to run in a state with 10 expensive media markets.
