The survey of 649 likely voters was conducted by phone over a three-day period last week. Its margin of error is 3.9 percent.
Amendment 60, which seeks to lower property taxes, only has 10 percent support in the survey. Forty-eight percent of voters are opposed to it while 42 percent remain uncertain.
Amendment 61, which seeks to restrict bonding and borrowing by government, is also only supported by 10 percent of those surveyed. It's opposed by 49 percent while 40 percent are uncertain.
Proposition 101, which seeks to lower income taxes and vehicle registration fees, is doing the best of the three tax measures, but still only 12 percent support in this poll. Forty-four percent opposed the measure and 44 percent are undecided.
The opponents of the three, Coloradans for Responsible Reform, have raised more than $5 million to defeat the measures.
"The general rule of thumb is that you want to be in the 50s or 60s at this point in time," said 9NEWS Political Analyst Floyd Ciruli. "That's because late deciders tend to go overwhelming against ballot measures. For the conflicted or the ill-informed, no is the safer vote."
Amendment 62, which seeks to define personhood at the moment of conception, is gathering 15 percent support from voters with 35 percent opposed and half of all voters still uncertain. It represents the sixth time in the last 15 years that Coloradans have voted on the topic of abortion.
Amendment 63, which seeks to give Coloradans the chance to opt-out of the federal health care reform law, enjoys the support of 10 percent of those surveyed with 19 percent opposed and 71 percent still uncommitted.
