Ron Paul’s other son, Robert, might run for Texas Senate

Another one of Ron Paul's children might be running for Congress.

Robert Paul, the congressman's fourth child and younger brother of Kentucky Sen. Rand Paul, tells the Fort-Worth Star-Telegram he's considering running for the seat being vacated by retiring Sen. Kay Bailey Hutchison.

"I have thought about running," Robert Paul, who runs a family medical practice in the Fort Worth suburbs, tells the paper. "I am very happy as a physician, but [I] have a lot of concern about the debt."

If he were to run, Paul would face a crowded GOP primary. Already at least two of the three declared candidates in the race--including former Dallas Mayor Tom Leppert and former state Solicitor General Ted Cruz--have raised more than $1 million for what is expected to be a hotly contested race.

Robert Paul tells the paper he hasn't yet started raising cash for his potential campaign--though a late entry didn't hurt his brother's bid in Kentucky. Rand Paul ultimately outraised an establishment-backed GOP rival with the help of his father's army of libertarian and tea party supporters.

The Texas doctor has some experience on the campaign trail. He was frequent surrogate for both his father's 2008 presidential campaign and his brother's Kentucky Senate race.

Interestingly, Ron Paul had previously been mentioned a possible Texas Senate candidate, though earlier this week, the congressman filed papers for a "testing the waters" committee ahead of his expected 2012 presidential campaign.
