Former South Carolina Gov. Mark Sanford ended his Republican presidential bid this week but he is more determined than ever to warn the nation of impending financial disaster.

Sanford challenged President Trump in the GOP presidential primary knowing full well his odds of winning were very low.  But he launched the bid anyway, seeing it as an opportunity to highlight the fiscal cliff our nation seems determined to fly off of. 

So why is Sanford ending the campaign?  

"All the oxygen was being sucked out of the room by impeachment, said Sanford, in an interview Radio America's Greg Corombos.  "I'm not into wasting my time or anybody else's.  It was a long shot."

But Sanford still plans to play a leading role in getting America to pay attention to the nation's debt and spending problems.  It comes at a time when the U.S. is running deficits nearing a trillion dollars under a Republican president.  Most Democrats running for president would greatly expand the role of government and the amount of money to be spent.

And don't even get him started on plans for government-run health care.

"It's financial insanity.  This is why I thought it was so important to try to raise my hand and say, 'I can't do this. I know I'm not going to become president but can we at least have a conversation about the fact that we're literally walking off the plank financially?'" said Sanford.

Listen to the full podcast to hear Sanford explain what awaits younger generations if Washington doesn't chart a different course, what approach is doable and would actually work, and what it will take for lawmakers to take the tough votes to rein in spending.
