It's really quite simple.

That's what I've been saying to those who still haven't decided. Cory Gardner quickly became the poster child of self-serving gimme politicians, setting new speed records in holding out his hand to the highest bidders. He'll sell out anyone - women, sick kids, immigrants, seniors, the environment - if the money into his pocket is big enough.

Mark Udall may not be perfect, but he has a long record of being on the side of everyone and everything that Gardner has thrown under the bus in the interest of his own personal advancement.
