Although ballots have been in most Colorado voters’ hands for more than two weeks – and as of Tuesday, 801,385 had been returned – spending to sway those who haven’t wrapped up their votes yet shows no cooling off in the state’s hottest races.

So which races are hot?

Based on spending by the two major committees, one is certainly the bid for attorney general. Colorado Freedom, an independent expenditure committee backed by the Republican Attorneys General Association, dropped $751,352 in the most recent reporting period between Oct. 11 and Oct. 24, and another $651,805 since then to support Republican George Brauchler or advocate against Democrat Phil Weiser.

The Democrats’ version, known as the Justice Colorado IEC, spent $872,836 between Oct. 11 and Oct. 24 and $122,000 since then to support Weiser or oppose Brauchler.

Spending on the five state Senate races considered key to which party controls it lit up during the last reporting period, and beyond. Independent expenditure committees run by and for Republicans have dropped at least $3.8 million on four of the five races. Committees backing Democrats have spent at least $3.8 million since Oct. 11.

The Better Jobs Coalition, which is run by Republican businessman Rick Enstrom of Lakewood, pulled in $1.5 million in the Oct. 11-24 period, including $400,000 from the dark money and pro-Second Amendment committee Colorado Citizens Protecting Our Constitution.

The Virginia-based GOPAC Election Fund, which also helps elect Republicans, has so far kicked in $450,000, including a $100,000 contribution in recent weeks.

Ready Colorado, a conservative group that backs education vouchers, kicked in $248,500, bringing their total to $298,500. The biggest donor, however, was the pro-business Vital for Colorado, which gave $700,000 in the last two weeks.

Where it was spent: $650,000 in the Adams County Senate District 24 race, to back incumbent Republican Sen. Beth Martinez Humenik and oppose her Democratic challenger, Rep. Faith Winter. The race is one of two now believed to determine control of the state Senate. The other is in Senate District 20, Wheat Ridge and Lakewood; Better Jobs spent $705,000 in the last two weeks to back Republican Christine Jensen and oppose the Democrat, Rep. Jessie Danielson.

The Business Opportunity Fund, which also backs Republicans, shelled out $658,000 between Oct. 11 and Oct. 24 to back Jensen and another $215,000 for Martinez Humenik, including $50,000 in the last few days.

The state GOP independent expenditure committee spent $300,000 on the two Senate races between Oct. 11 and Oct. 24, as well as on two others – the Senate District 16 seat held by incumbent Republican Sen. Tim Neville of Littleton, and the open seat in Lakewood’s Senate District 22 that is being sought by Republican Tony Sanchez.

But the spending since Oct. 24 is staggering: $1.13 million for those four state Senate races.

Coloradans for Fairness, the main committee backing Democratic candidates for the Senate, dropped $3.1 million between Oct. 11 and Oct. 24, and another $717,000 since Oct. 25. While the committee’s spending has backed at least a half-dozen candidates, the biggest bucks are being spent on the same races: Senate District 20 and Senate District 24.

The committee spent at least $1.25 million on the Martinez Humenik/Winters race, including $200,000 in the last week, and another $1.178 million on the Danielson/Jensen race, with $250,000 in the past week. Most of the rest went for the three other top races, between incumbent Democratic Sen. Kerry Donovan for the Senate District 5 seat on the Western Slope, to back Rep. Brittany Pettersen for the Senate District 22 seat, and to support Tammy Story, who’s running against Neville.

But there’s a sixth seat that Democrats are looking at, based on the most recent spending by Coloradans for Fairness.

Republican Sen. Kevin Lundberg of Berthoud is term-limited, so that’s an open seat that’s now drawing the committee’s largesse. Voter registration numbers from September show Democrats at a distinct disadvantage in Larimer County-based Senate District 15, but the committee has spent at least $111,000 in the last two weeks to support the Democratic contender, Rebecca Cranston.
