As a Congressman, Bob Beauprez usually isn't dealing directly with the same issues he would as governor. Immigration is one counterexample, where he's helped sponsor a tough border control bill. So are taxes, where in 2003, he supported a bill to reduce capital gains, dividend, and income taxes.
Another is the House leadership race. Rep. Beauprez hasn't yet announced a candidate to support, but he's a member of the fiscally conservative Republican Study Committee, led by Rep. John Shadegg. Shadegg is a reliable conservative, fiscally sound, and squeaky-clean ethically. At issue is both what Rep. Beauprez does and what the RSC as a whole does.
Rich Lowry has pointed out that waiting too long to endorse might doom Shadegg's candidacy. It might also provide cover to people who don't really want him elected.
While, as Michael Barone notes, there's little point in handicapping such a race, and the that doesn't mean we can't ask the representatives who they're backing. The vote may be private, but public statements are on the record. If Beauprez were to make a strong public statement in favor of Shadegg, or to argue that the RSC should declare now rather than later, it would make a strong impression on conservatives who want the party to clean up its act for real.
Beauprez does operate at something of a disadvantage, since he needs to deal with practical issues as an elected official, in a way that Holtzman does not. The House leadership race can provide one barometer of where he wants the party to go when it's under pressure.

UPDATE: A commenter points out that the National Journal is reporting Beauprez as committed to Blunt. The date of the posting is 1/14, which suggests that it was working off a slightly older list than that. This was before, or close to, the time Shadegg actually announced, at a time when Blunt was trying to sell the fiction that he had it all locked up.
Even public committments are next-to-impossible to enforce. Beauprez could argue that he committed too early & he's sorry about that, but that Shadegg hadn't yet entered the race and, after all, it's better to say something publicly rather than do the traditional private-ballot back-stabbing thing and wait until the vote.
