A study commissioned by Sen. Tom Coburn is casting doubt on whether taxpayers' $18 billion annual investment in federal jobs training programs is paying off.

"The vast majority of money we spend in job training doesn't go to job training, it goes to employ people in those job training federal programs," Coburn told  Fox News.

The 2011 Government Accountability Office study he commissioned, which examined programs in fiscal year 2009, found an overlapping and duplicative maze of 47 federal jobs programs run by nine agencies. Some were rife with mismanagement, waste, fraud, abuse and corruption.

The study found:

• Some job training participants spent their days sitting on a bus.
• Some were trained for jobs that didn't exist.

With Mitt Romney's GOP presidential nomination all but decided, Ron Paul supporters took control of the Maine Republican Convention and elected a majority slate supporting the Texas congressman to the GOP national convention, party officials said. The results gave the Texas congressman a late state victory.

In votes leading to the close of the two-day Maine convention, Paul supporters were elected to 21 of the 24 delegate spots from Maine to the GOP national convention in Tampa, Fla. The 24th delegate's seat goes to party Chairman Charles Webster, who has remained uncommitted throughout the process.

Making the Paul takeover complete was the election of Paul supporters to a majority of the state committee seats. "It's certainly a significant victory," said Jim Azzola of South Portland, Cumberland County coordinator for Paul.

Sarah Palin's qualifications are what earned her the spot as Sen. John McCain's running mate in the 2008 presidential elections, he told Jake Tapper on ABC's "The Week" on Sunday.

When asked what should be considered in the choosing of presumptive GOP presidential nominee Mitt Romney's vice president, McCain said the "primary, absolute, most important aspect is if something happened to him, would that person be well qualified to take that place?"

The former POW said this was a major factor in his selection of Palin as his running mate. "I happen to believe that was the ... primary factor on my decision in 2008," he said, "and I know it will be Mitt's." He added that having a "person [Romney] knows he could trust," is an important factor.

Palin was heavily criticized during and after the 2008 campaign for being ill fit to assume the role of president if need be.
