Well gee, now that you ask, I can't find it!
Honestly.
I saw the number 64% and 66% in two different polls over the last 3 days. One was reported on Drudge, the other was reported on the radio, and I saw a local news cast last night that used a graphic with one of those two numbers on it. At first, I didn't believe it, but did a double-take and confirmed what I was seeing -- it was something like 64% opposed to the current stimulus package. Then the other numbers were something like 14% in favor, with the remaining being unsure. But now I can't find it, which makes me think it was one of those numbers that was generated from a specific question in the poll.
The poll results I am seeing now show a strange result: 56% in favor of "an economic stimulus plan" or "in favor of taking action on the economy" or something along those lines. So, again, I promise I saw those numbers, but what I see today may indicate that those results are buried in the specific polls someplace.
I guess I was wrong, till I can prove otherwise -- sorry.
On the other hand, I'm a teacher, I'm surrounded by people who are still getting together after work to celebrate the election -- NONE of them are in favor of this bill. They are in favor of some economic stimulus plan, but not this.
