Just yesterday, former Rep. Joe Sestak announced he was entering the Democratic primary, bringing the count to 24. That’s right, folks, two dozen Democrats are now vying for the chance to run against Donald Trump in 2020.
Historically, being elected President while a member of the House - or having most recently served in the House - is rare.
From what I can tell, only two were ever elected in this way - Lincoln and Garfield (by some odd coincidence, both shot)
and Lincoln hadn't held an office in several years before he ran.
There were a few others - such as most recently, Ford - but they were never elected President.
Running for President while a member of the House is a long shot. But several Vice-Presidents and VP candidates
have been Representatives.
In the last century, your best bet has been being a governor.
