We have grown used to long presidential campaigns. Those begin the day after the "off-year" election ends, and we ought to expect "exploratory committees" and even formal declarations of a campaign for the presidency to pour forth in November and December of this year.
GOP Chairman Reince Priebus may hold off the onslaught of presidential primary debates by pushing out an official schedule of 2015-2016 RNC-sponsored debates in late summer or early fall of this year, which would allow top tier candidates to waive off all other invites, but even if sanity returns to the debate process the new schedule of primaries and the ever-present need to raise big dollars for a long campaign means you can hear the engines being turned over on possible presidential campaigns already.
We are used to that. What we aren't used to is a long Congressional campaign like the one already begun. Take a look here at Tom Cotton's wonderful ad against Mark Pryor which released yesterday. This is wonderfully effective 30 second spot (especially when you consider that Arkansas Senator Mark Pryor is himself the real "entitled" candidate having inherited his Senate seat from his dad), and it is the sort of ad that used to emerge after Labor Day when campaigning picks up in a steadily growing crescendo. But it isn't even Memorial Day yet. It isn't even May! Cotton is out raising and hammering Pryor like an anvil with six months of sprinting left ahead. So it is in many other Senate and House races. So it will continue to be.
