Mark Sanford announced on Sunday that he is running for president, making him the third Republican to go against President Trump’s reelection attempt. He joins former Massachusetts Gov. William Weld and former Illinois Congressman Joe Walsh. Despite little chance of winning against Trump, here is what they represent:

Mark Sanford served as a U.S. Representative for South Carolina’s 1st congressional district from 1995 to 2001 and 2013 to 2019. Sanford won the 2002 South Carolina gubernatorial election, wherein he defeated the Democratic incumbent Jim Hodges. He was re-elected in the 2006 South Carolina gubernatorial election, and consequently served as Governor of South Carolina from 2003 until 2011.

Former South Carolina Gov. Mark Sanford announced Sunday that he is running for president as a Republican, becoming the latest to challenge President Trump in the GOP primaries.

In a series of tweets, Sanford explained the reasons why he was entering the 2020 race as a republican:

“I am compelled to enter the Presidential Primary as a Republican for several reasons – the most important of which is to further and foster a national debate on our nation’s debt, deficits and spending.

We have a storm coming that we are neither talking about nor preparing for given that we, as a country, are more financially vulnerable than we have ever been since our Nation’s start and the Civil War. We are on a collision course with financial reality. We need to act now.

As I have watched the Democrat debates I hear no discussion, or even recognition, of what is occurring. Instead I hear a laundry list of new unpaid for political promises. On the Republican side, spending is up well above President Obama.

Donald Trump has ruled out action on the very things that drive spending and accumulated debt. Debate is even being cancelled on the Republican side, though I believe we need a conversation and action more than ever given our present course.”

William (Bill) Weld is an American attorney, businessman, and Republican politician who served as the 68th Governor of Massachusetts from 1991 to 1997. He also served as U.S. Attorney for the District of Massachusetts.

The Former Massachusetts governor announced back in April in an interview on CNN that he would challenge President Trump for the 2020 Republican presidential nomination.

“Donald Trump is not an economic conservative. He doesn’t even pretend to be. The country deserves to have some fiscal constraint and conservatism,” Weld said. “I’m not saying I would ever endorse a Democrat in but I could not support the president.”

“Trump and his allies and the Republican National Committee are doing whatever they can do to eliminate primaries in certain states and make it very difficult for primary challengers to get on the ballot in a number of states,” Walsh told Politico. Weld reacted by tweeting, “Donald Trump, by turns arrogant and paranoid, has made no secret of the fact that he wishes to be crowned as president rather than elected. That might be fine in a monarchy, but we overthrew ours two centuries ago.”

Joe Walsh is a conservative talk radio host, who served one term in the United States House of Representatives representing Illinois’s 8th congressional district.

Walsh announced in August on ABC’s “This Week” that he’s launching a long-shot Republican presidential primary challenge against President Donald Trump.

“I’m running because he’s unfit; somebody needs to step up and there needs to be an alternative. The country is sick of this guy’s tantrum — he’s a child,” responded Walsh to Stephanopoulos when he pointed out the massive uphill climb Walsh has in front of Trump in the 2020 primary.

“He [Trump] believes and acts like he is above the law. If we give him four more years, heaven help this country,” said Walsh in an interview with MSNBC on Friday.
