One thing about 2016 GOP presidential speculation

[MASHED POTATOES. VOTE!]

Assuming, of course, that field in 2016 will be widely open (AKA: no incumbent).

We seems to forget one key element while mentioning possible candidates like Marco Rubio or Rand Paul: 2010 freshmen class.

They are going to be up for reelection the very same year. And that is making a politician less likely to run for President. The most recent and most prominent example is John Edwards, retiring to run for President after one Senate term, thus skipping reelection. He didn't end up well.

Of course, in some states you can run for Senate and Presidency at the same time, but I don't think anyone would dear to pull "Lyndon Law" while running for President. Vice President is a diffrent thing, but that'd would certainly backfire.
