Hillary Clinton hasn't even stepped down yet as secretary of state and there's already constant speculation as to whether she'll run again for the White House. While no decision from her on any future bid for president is expected in 2013, expect speculation about her future political plans to intensify throughout the new year.

Same thing, on a lower level, for Vice President Joe Biden.

On the Republican side, we're already starting to look at Sen. Marco Rubio of Florida, Rep. Paul Ryan of Wisconsin, Gov. Bobby Jindal of Louisiana, Sen. Rand Paul of Kentucky, former Gov. Jeb Bush of Florida, former GOP presidential candidate Rick Santorum of Pennsylvania, and Christie, through the 2016 prism.

In reality, with the real start of the 2016 campaign still about two years away, now's the time for these possible candidates to make speeches, meet and greet donors, campaign for fellow Republicans in the 2013 and 2014 elections, and write books.

And we'll be here to cover it all.
