Former South Carolina Gov. Mark Sanford, who is one of three Republicans that are challenging President Donald Trump for the 2020 GOP presidential nomination, began an eleven state swing in Pennsylvania on the importance of addressing the deficit on Wednesday.

“My intention and purpose is to begin a national dialogue with voters about our nation’s disastrous financial state,” Sanford said in a release about his “Kids, We’re Bankrupt and We Didn’t Even Know It” tour. “I continue to be perplexed and amazed by the ways in which President Trump and my would-be democrat presidential opponents have stayed silent on this critical issue.”

Sanford kicked off the week-long tour in front of Independence Hall in Philadelphia on Wednesday morning, holding a large “one trillion dollar” check that was intended to symbolize the burden of the national debt. The Philadelphia Inquirer reports that just one person showed up for the launch of the tour, but still he discussed his hopes to “spark a needed conversation” within the Republican Party about spending and debt.

Sanford’s second stop of the day was in Harrisburg at the state capitol and ended the day by talking with customers at several restaurants in Pittsburgh on Wednesday evening. 

The Pennsylvania Republican Party unanimously endorsed Trump for the Republican nomination at their most recent state committee meeting. Real Clear Politics shows Trump consistently receiving at least 80% of support in the primary, while challengers Sanford, former Illinois Congressman Joe Walsh, and former Massachusetts Governor Bill Weld all register in the single digits. 

Sanford acknowledged the longshot nature of his bid, but said the financial situation warranted the primary bid. 

“I’m not delusional about electoral prospects. I know what a ‘David and Goliath’ story this is, how uphill it is,” Sanford said to KDKA. “But I know on behalf of my four sons and a lot of other kids and grandkids that are out there that if we don’t address this, we’re going to face the most severe financial storm our nation has ever faced, I mean along the lines of the Great Depression.”

A full day in Philadelphia, Harrisburg, & Pittsburgh. On to the #Buckeye state tomorrow! @realdonaldtrump should take a page from the Founding Fathers’ designs on political norms & beliefs in institutions designed to limit and divide power. pic.twitter.com/ML9m7zJS1g
