Someday, sure. I think Gardner will be a far stronger candidate though.
What makes Gardner a strong(er) candidate?
Well, he basically was elected in 2010 as a culture warrior and has since represented Greeley and the eastern plains as a culture warrior. At this point, he is 3 points ahead against a solid incumbent senator by successfully denying he is a culture warrior yet still being overtly committed to being one. Anyone who can pull off what Gardner is pulling off is at least VP material. Then again, this could just be because Udall is "trying to hard". But even then, he was just known as someone who was very smooth in a state where the Republican bench has a reputation of being very awkward.
Tom Cotton is just helping solidify a red state while Gardner is doing something much more impressive.
Gardner was also Congressman for 4 years before becoming a Senator. Obama was a first term senator when he became president, right? Though, he will be campaigning in his second instead of third and forth year. He'd definitely be a good choice. He can triangulate, fire up the base and is from a state Republicans need.
