We've been talking about Q4 (2013) fundraising numbers for Colorado's U.S. Senate candidates, but the stunningly-poor quarter turned in by the three leading GOP contenders (Ken Buck, Owen Hill, Amy Stephens) is difficult to fully appreciate without looking at comparisons.

We looked at fundraising numbers for (serious) Senate candidates in Colorado, considering only the 18 months prior to Election Day, and the comparisons are pretty incredible. In the chart below, we outline the 10 worst fundraising quarters for U.S. Senate candidates since 2000.

The numbers speak for themselves: Buck, Hill and Stephens just turned in 3 of the worst fundraising quarters in the last decade. All told, the GOP triumverate are responsible for 5 of the 10 worst fundraising quarters in 13 years:

CANDIDATE QUARTER AMOUNT RAISED 1 Mike Miles (D) Q3 2003 $28,201 2 Mike Miles (D) Q4 2003 $33,877 3 Ken Buck (R) Q4 2009 $45,585 4 Amy Stephens (R) Q4 2013 $51,000 5 Mike Miles (D) Q1 2004 $56,701 6 Mike Miles (D) Q2 2004 $88,576 7 Tom Wiens (R) Q2 2010 $99,962 8 Owen Hill (R) Q4 2013 $109,000 9 Ken Buck (R) Q4 2013 $154,109 10 Ken Buck (R) Q3 2009 $159,074

Here's one more amazing comparison as you ponder the GOP's money woes: Republican Rep. Mike Coffman actually SPENT more money in Q4 than any GOP candidate for Senate was able to fundraise.
