(CNN) Massachusetts Sen. Elizabeth Warren's presidential campaign is, to quote NBA Jam, "on fire". The latest Quinnipiac University national poll out today has Warren at 27% to former Vice President Joe Biden's 25%.

Now, one poll doesn't mean much, and Quinnipiac's result is well within the margin of error, so there's no clear leader. But when you put Quinnipiac's latest into the context of other recent polls, it's pretty clear that Warren is gaining everywhere.

Warren's national numbers are up since the September primary debate. She comes in with an average of 23% in debate qualifying polls taken after the debate. That's still behind Biden's 28%, but not by much. The trendline is what is important here. Warren was at 18% in an average of qualifying national polls taken in September before the debates.

The 5-point climb for Warren post-debate seems to be a continuation of a trend we've seen for months.

In an average of debate qualifying polls taken before the first set of debates in June, Warren was 12%. That rose to 16% in July. In other words, Warren's increasing numbers are the result not of one moment but of many.
