First: I have tabs open to HuffPollster's national average, HuffPollster's big map, and RCP's national average. I've been insanely, irrationally hitting refresh on the HuffPollster national average...well, often enough to know that the lead flipped at least four times yesterday. Only
I try very hard to ignore the individual national polls I see over twitter. I'll admit to one bad habit: I'm one of those foolish souls who checks Gallup every day when the new numbers show up. But it's more of a ritual than it is information gathering. For state polling, Taegan Goddard's Political Wire does a great job of collecting the day's polls -- especially if you don't use twitter he's still tops, and if you do you should of course follow him. It's a good way to get a quick look at a bunch of state polls without getting distracted by any particular one. If I see something that stands out, I'll switch over to the HuffPollster big map and click on that state.
That's pretty much the numbers. I'll look at other things once in a while, and I'm aware of what the poll-based predictors say, but I haven't been checking them regularly. That's pretty much what I'm doing.
On top of the numbers, I mostly read Nate Silver's daily summaries, and whatever Mark Blumenthal writes over at Pollster, plus I look for Harry Enten and Nate Cohn, try to be aware of what Sean Trende is saying, too. Plus I try to read anything that political scientists who blog about polling and elections write (Drew Linzer and Simon Jackman in particular on the numbers, but of course anything at Monkey Cage, Brendan Nyhan, etc., etc.). There are other good people out there, too, and I'll come across those, but that's my basic run. The idea is to be aware of any additional texture or biases in the numbers we're seeing -- but at the same time it's really important not to get into cherry-picking.
I think that's basically it.
I'll also check Nate Silver or Pollster for Senate races, and I see Senate polls posted on twitter. I wish I had more House info.
The only really strong recommendation I'll give you is the basic one: polling averages, not individual polls. The rest? Look, there's no reason to do any of this; we'll find out soon enough who wins the presidency. So this is strictly about what to do if you're a semi-obsessive political junky...you really, really, really want more info, but you also want an honest evaluation of what's going on.
