Independent Greg Orman continues to lead Republican incumbent Pat Roberts in Kansas’s unexpectedly competitive Senate race, with two new polls showing Orman with a small lead.

The latest Rasmussen survey shows Roberts trailing by five points, the biggest gap in weeks for the Republican, with Orman at 49 percent to Roberts’s 44 percent. Three percent say they will support another candidate, and 5 percent are still undecided.

Meanwhile, a Gravis Marketing survey is more in line with other recent polls, which have shown the race within the margin of error. Orman has a slight edge, 47–45, with a 3 percent margin of error. Another 8 percent are undecided.

Roberts has either led or been within the margin of error in every poll since the beginning of the month, with the exception of the new Rasmussen one.
