In this case, it happens to be about Mark Udall's nearly-convinced appeal in favor of the so-called Employee Free Choice Act (EFCA).
The initial question is part of a broader ad campaign by a group called Coloradans for Employee Freedom that questions Mark Udall's support for EFCA and wonders aloud: "Shouldn't your vote still be private?"
As the Daily Blogster puts it:
One value (VOTING) is extremely sacred to Americans and all freedom loving people around the world but Udall wants to make an exception when it comes to one of his most sacred of institutions....labor unions.Which - going out on a limb here - may have something to do with hundreds of thousands of dollars in Big Labor campaign contributions.
After all, Mark Udall co-sponsored EFCA despite admitting "serious reservations," and acknowledged to the Denver Post that the legislation "isn't perfect." That's a nice way to describe depriving millions of workers the right to a secret ballot in workplace elections. After lo these many months, Mark Udall still hasn't had to explain how he can be so out of step with Coloradans and Western values.
