We now have three polls released in the last five weeks showing vastly different results.
The first was an internal poll by the National Republican Congressional Committee that touted a whopping 15-point lead for Love. Two weeks ago, Dan Jones released a poll that showed Love leading, but by a considerably smaller margin, holding a six-point advantage.
Now we have the House Majority-Center Forward poll of 407 likely voters conducted Oct. 9-10. It has a margin of error of plus-or-minus 4.9 percent.
A note about internal polls that really should go without saying: They typically need to be taken with a grain of salt, because they are released with a reason, generally to tout their own candidates' strength.
There are two things worth noting, one that could bode ill for Matheson, one that points to the race remaining a coin toss.
First, Matheson is not over 50 percent in any of the three polls, which is usually where an incumbent would want to be. I would think that is especially true this year, where everyone is expecting a strong Republican turnout.
Second, the Dan Jones poll had an 8 percent undecided, and the House Majority-Center Forward poll had 11 percent undecided. That would seem to indicate that how the undecideds break could still decide the winner in the Fourth.
UPDATED: So I got a fascinating number from the new 4th District poll that points out what will be a deciding factor in the 4th District race.
You may have seen my story over the weekend, looking at the importance of women voters a group that Matheson had consistently won by double digits and, according to the Dan Jones poll, now trails by 10 points.
The House Majority-Center Forward poll, however, paints a very different story: Their poll shows Matheson crushing Love among women voters, by a margin of 54-36.
That's a big margin and a stark contrast to the Dan Jones poll. It also would indicate Matheson is trailing among men, which would be in line with Matheson's results from 2010.
It's hard to know which is correct, but I think it reinforces what BYU Political Science Professor Adam Brown said in my weekend story: "The outcome of this race probably depends on how women vote."
