As you can see, the numbers on the questions we ask regularly barely shifted over the last two weeks — in other words, a totally normal and expected result. (The only notable change belongs to Nancy Pelosi; I'll be really curious to see if she's on any kind of upward trend, but she's pretty much stayed in the same band over our last five polls.)
I do want to revisit another set of numbers that does typically see some movement, though: party self-identification. As I discussed last week, sometimes people's attitudes about elected officials change on their own, while sometimes they change in concert with their views of themselves. There are many reasons for these shifts, but one thing pollsters and political scientists know well is that there are very few "true independents" — folks who are equally apt to vote for both parties. Most self-described indies actually lean one way or the other, which means that with the right nudge, they could very well start identifying themselves as either Democrats or Republicans.
But what's really interesting is that in our poll, those nudges (whatever they may be) seem to keep shoving people back and forth between D and I — Republicans just aren't budging. Take a look at this visualization created by Tableau Software:
