Washington (CNN) -- Former Republican presidential candidate Newt Gingrich offered Maryland Gov. Martin O'Malley some advice Sunday on running for president.
"Raise a lot of money," Gingrich told the rising Democrat on NBC's "Meet the Press." "It's the entry level problem. You've got to be prepared."
Gingrich was greatly out-funded by his chief rival Mitt Romney during the GOP primary process and ended his campaign after a tumultuous road in early May.
The former House speaker described the trek as "tough," but said he has no regrets, despite some bruising months.
"Understand you'll spend two or three years on the road," Gingrich said. "This has been a brutal, tough process at least since 1800 ... If you're not tough enough to get the presidency, you're not tough enough to be president."
If O'Malley, the chairman of the Democratic Governors Association, needs any evidence of the obstacles, Gingrich suggested he talk to former Virginia Gov. Mark Warner, who decided against a 2008 White House bid.
"Mark Warner's a great guy to talk to because he went out, he looked at it a lot, and he came back and ran for the Senate," Gingrich said.
Warner, now a U.S. senator, announced in 2006 he would not seek the presidency, citing the personal toll a run would likely take on his family.
O'Malley, the two-term governor of Maryland and former mayor of Baltimore, is often floated as a potential Democratic presidential candidate for the future, talk he did little to quell on Sunday.
"I haven't even thought that far," O'Malley said on the same NBC program. "I'm focused on what I'm doing right now, which is doing everything in my power to help elect Democratic governors."
