WASHINGTON (CNN) -- Sen. Joe Biden, D-Delaware, formally jumped into the 2008 presidential race Wednesday, two decades after he first sought the White House in 1988.

But Biden isn't the first person to run for president, wait 20 years, and then run again. Ohio Governor "Fire-Alarm Joe" Foraker, a Republican, ran unsuccessfully in 1888; as a senator, Foraker ran again in 1908. He failed miserably both times, which may explain why he waited 20 years between White House bids.

More recently, Idaho GOP Senator William Borah, "the Lion of the Senate" waited even longer -- 24 years -- between presidential campaigns. He ran a favorite-son candidacy in 1912, then laid low until 1936 when he won a string of victories in the primaries before losing to Alf Landon, the Governor of Kansas, at the convention. Landon went on to lose to President Franklin D. Roosevelt in a landslide that year.

Numerous other politicians have run for president over two decades, including Henry Clay, John C. Calhoun, and William Jennings Bryan. Unlike Biden, Foraker and Borah, these men ran multiple times during the decades in question.
