Colorado's Rep. Boebert in unexpectedly close race as control of House remains on a knife's edge.

The surprisingly close race in Colorado's 3rd Congressional District remains in a holding pattern on Monday, with U.S. Rep. Lauren Boebert, the Republican incumbent, still leading Democratic challenger Adam Frisch by a razor-thin margin. The fact that this race remains too close to call is one of the biggest surprises to come out of this year’s midterms. The third congressional district hasn't elected a Democrat to Congress since 2008. It was made even more favorable to Republicans when its borders were redrawn last year.
