When you're the President of the United States, you are one of the most watched people on Earth. Everyone knows where you are and what you're doing at all hours of every day you're still the President. But on the day the new guy shows up and throws you out of the White House? Boom, no one cares anymore.
That may seem a little harsh at first glance, but just answer this one question: what is George W. Bush doing right now? I've got no idea either. Even
his Wikipedia page only goes up to September 2011, over a year ago. All I know is that he's no longer involved in Washington, D.C., and I'm fairly relieved.
While Bush seems to have given up the political realm so far, some former Presidents just couldn't shake the urge to be a politician. I'm not talking about the guys who ran for a second term and lost, I'm talking about the ones who apparently sold their homes outside of Washington and never wanted to leave. People like:
John Tyler
John Tyler was the first Vice President to assume the role of President after William Henry Harrison died only 32 days into his term. This sparked a huge controversy over whether Tyler was actually the President or just the "Acting President," who would serve until someone else would be elected. Long story short, Tyler took the oath of office and became the President.
As if that wasn't enough controversy for one term, he also
essentially stole Texas from Mexico. He held this off until late in his term because he thought that this would help him get reelected as an Independent in 1844 because he had
pissed his party off so much that they tried to impeach him, but instead wound up sticking his successor with the gritty details (in this case meaning war).
Mostly because of the whole alienating-his-entire-party thing, Tyler is often considered
one of the worst Presidents. But hey, it's not like started the Civil War or anything. That was all Buchanan.
The Post-Presidency
While it's not entirely true that Tyler started the Civil War, he did less than nothing to stop it. After retiring to Virginia and doing some
hilarious things shortly after his Presidency ended, he reentered politics in early 1861 during the
Virginia Peace Conference, which was a last-ditch effort to stop the Civil War. When that didn't work, Tyler started openly advocating for Virginia's secession. After the war broke out, he immediately sided with the South, going so far as to serve in the Provisional Confederate Congress. That's right, a former President of the United States was now serving in the Confederate government.
Tyler was actually elected to the actual Confederate Congress, but died before he could take his seat. His death is the only time in US history that the federal government hasn't officially recognized a former President's death, mainly because he was working for the enemy at the time.
William Howard Taft
Consistently voted "Best Mustache" of all Presidents
William Howard Taft was the 27th President, and directly succeeded Teddy Roosevelt in office. Taft was Teddy's good friend and Cabinet member, and was the person most likely to follow Roosevelt as the President. Despite this, he was never really sure if he wanted to be President, instead wishing to be a Supreme Court Justice. He apparently made this clear to Teddy, but wasn't appointed.
So Taft, with Roosevelt's support, ran for President. Teddy thought that Taft was a true
Progressive like he was, but Taft showed that he was more traditionally Republican. Taft was still a Progressive, but not nearly as progressive as he was expected to be. Not helping matters was the fact the Roosevelt, the man who essentially pushed Taft into the White House, left on an African safari almost as soon as he left Washington. Taft was left without the wisdom of his mentor, and because he followed many precedents without question, he was a considerably weaker President that Roosevelt.
Naturally, Teddy was not happy about this. After returning from Africa, he declared that he would run for President again in 1912. When he couldn't pick up the Republican nomination (our political parties will always renominate the incumbent, regardless of popularity, as evidenced by this example and that Herbert Hoover, the guy with no popularity during the Great Depression, got renominated), Teddy formed his own party (the Bull-Moose Party) and ran on that ticket. In
the 1912 election, Roosevelt actually beat Taft in both the electoral college and popular vote, but the split in the Republican party allowed Woodrow Wilson to win.
The Post-Presidency
Remember how Taft always wanted to be a Supreme Court Justice but Teddy would never let him? Apparently he never gave up on that dream. After working for Yale for a while and running the
National War Labor Board during WWI, Warren G. Harding nominated Taft for the vacant spot of Chief Justice. Taft was overjoyed, and the Senate approved him with a 60-4 vote. He served on the Court for 9 years until shortly before his death.
