Coloradans appear inclined to let the state keep their TABOR tax refunds and spend the extra money on education and transportation, according to a poll released Wednesday by the Republican firm Magellan Strategies.

The survey of 500 likely voters found 54% said they would vote yes on Proposition CC after a pollster read them the ballot language. Conducted by phone and online, it found that 30% would vote no and 15% were undecided.

The Democrat-controlled General Assembly put Proposition CC on the November ballot during the 2019 legislative session. It asks voters to unwind the part of the Taxpayer Bill of Rights that limited how much government could grow. The constitutional amendment created formulas for how much tax revenue state and local governments could keep each year, and anything above those limits had to go back to taxpayers. Most Colorado cities and counties have already done this, but the state remains bound by the TABOR spending cap.

The poll had a margin of error of 4.38%, which means the measure’s lead is within that margin. The results are still good news for supporters, though. The pro-CC campaign has yet to launch while the No on CC campaign has been canvassing, knocking on doors and sending mailers for weeks.

The survey, which was conducted between Aug. 5 and 7, also found strong general support for the TABOR amendment.

It had a 46% favorable rating and 36% unfavorable before pollsters explained how it worked. When asked whether raising taxes should require voter approval, “total support” for that provision rose to 62% while “total opposition” dropped to 26%. Even among registered Democratic voters, Magellan found that 52% support this limit on government.

“We believe the survey findings validated a popular belief that the full repeal of TABOR, even in a presidential election cycle with significant unaffiliated and younger voter turnout, is unlikely,” Magellan wrote in its polling memo. “However, it remains to be seen if a well-funded voter education campaign to weaken or repeal TABOR would be effective.”

The Colorado Fiscal Institute, a left-leaning nonprofit, is currently exploring different TABOR repeal ballot initiatives for the 2020 ballot.
