Mt. Virtus has some early Senate poll numbers. It's all name recognition at this point, but Schaffer is only trailing Salazar 88% - 70% at this point, which is nothing.

UPDATE: Colorado Conservative, apparently not offended by my call-in to his radio show a few weeks ago, reports that Liniger has chosen to make a different use of his hot-air - ballooning - rather than run for the Senate. So it looks like it's Salazar vs. Schaffer, with Salazar now having to spend at least a little money to get past the primaries.
