While he has been on the Texas political stage for more than three decades, Ron Paul has not fared well there when he has made his two previous presidential bids -- but he hopes the third time will be the charm as he ramps up operations in the Lone Star State this week.

Now making his third try for the White House -- and second attempt at the Republican presidential nomination -- Paul has turned his eyes to Texas, which will bring 155 delegates to the GOP convention in Tampa come August. Texas holds its primary May 29.

The two leading Republicans aiming to challenge Democrat incumbent U.S. Sen. Bill Nelson in November looked to advance their campaigns on Tuesday in very different ways.

Congressman Connie Mack, whose father held the Senate seat for 12 years before stepping down in 2000 when Nelson won it, released a radio ad on Tuesday that will run across the Sunshine State.

In the ad, Mack takes aim at President Barack Obama and Nelson on gas prices, slamming the two Democrats for opposing the Keystone XL Pipeline which would bring oil into America from Canada.

After ripping into the GOP over the weekend, former presidential contender Jon Huntsman on Tuesday reiterated his commitment to backing Mitt Romney -- but remained critical of the near-certain Republican nominee.

Mike Hayden knows a thing or two about terrorists. From 2006 to 2009, he ran the Central Intelligence Agency.

Appearing on Americas Newsroom on Fox News on Tuesday, former Minnesota Gov. Tim Pawlenty talked up U.S. Sen. Marco Rubio, R-Fla., to be Mitt Romneys running mate.

Having come close to ending up on the 2008 ticket as John McCains running mate, Pawlenty, who had been in the Republican presidential race before pulling out after a disappointing third-place finish in the Iowa GOP straw pollin August, insisted he has no interest in being paired up with Romney.

With the General Services Administration under fire for a costly event held at the M Resort in Las Vegas back in 2010 on the taxpayers dime, a congressman from Florida introduced a measure on Tuesday to slash federal travel funds.

From his perch on the Oversight and Government Reform Committee and as chairman of the Federal Workforce, Postal Service and Labor Policy Subcommittee, U.S. Rep. Dennis Ross, a freshman Republican, unveiled the Government Spending Accountability Act.

With the number of Secret Service members and agents caught up in the partying-with-prostitutes scandal in Cartagena now at a dozen, and six already gone, how much wider and deeper does this go?

Preparing for Florida's shift to a statewide Medicaid managed-care system, 20 health companies and organizations are interested in competing for contracts to serve seniors who need long-term care.

Potential bidders faced a deadline last week to submit nonbinding letters of intent that signaled their interest in the long-term care program, as the state Agency for Health Care Administration gets ready to move forward with a lengthy contracting process.

Republican insiders say Jeff Atwater's decision to stay out of the U.S. Senate contest means it's now Rep. Connie Mack IV's race to lose.

Some say Mack is doing a pretty good job of it.

Javier Manjarres, the Shark Tank blogger who broke the story that Atwater was "considering" a run, said the courting of the state's chief financial officer "showed that grassroots/tea party activists around the state are not convinced that either Congressman Connie Mack or former Senator George LeMieux can beat Democratic Senator Bill Nelson."
