Matthew McConaughey won't rule out running for Governor of Texas

He's starred in many movies and has just written a book, but Matthew McConaughey is keeping his cards close to his chest when it comes to his political ambitions. 

Asked on the Hugh Hewitt radio show whether he might consider running for Governor of Texas, McConaughey was undecided - but certainly not entirely opposed to the idea. 

"It would be up to the people more than it would me," he replied. 

The Dallas Buyers Club star did stipulate that he'd like to see the political system and the ethos behind it improve before he took part, however. 

"Politics seems to be a broken business to me right now. When politics redefines its purpose, I could be a hell of a lot more interested," he said. 

McConaughey was further pressed on the issue when he appeared on the Late Show with Stephen Colbert, where he insisted he "didn't get politics" and "had no plans" to run right now - an answer that Colbert called out as "the perfect political response". 

Despite his protests, the 51-year-old actor and producer did admit he would consider a change in career as he got older. 

"As I move forward in life, yes, am I going to consider leadership rules where I can be most useful? I'd love to. I'm already doing that regardless," he said.
