From Heath Haussamen's nmpolitics.net:

Most voters in poll give Heinrich a thumbs-up
By Heath Haussamen • 3/14/10
The majority of those who voted in last week’s non-scientific poll on this site said they approve of the job Martin Heinrich is doing as U.S. representative for the 1st Congressional District.

Of 1,252 voters, 835, or 67 percent, said they approve of the job Heinrich is doing, while 399, or 32 percent, said they do not, and 18, or 1 percent, said they don’t know.

To be noted: this is a voluntary straw-poll - NOT a statistically-based so-call 'scientific' poll. As Mr. Haussamen states, "Dont' read to much into" the results!
[Again I wonder: why did those 18 "don't knows" bother to click the button?]

This week's poll:

Do you approve of the job Ben Ray Luján is doing as U.S. representative for the 3rd Congressional District?
