Because it looks like the big corporate fat cat donors are not supporting the Republicans as one would expect:

Last month, the Democratic Congressional Campaign Committee just about doubled the haul of their counterparts, the National Republican Congressional Committee. The DCCC pulled in $6.64 million, while the NRCC brought in just $3.8 million. While the NRCC has more cash on hand (around $12.2 million to the DCCC’s around $9.5 million) and slightly less debt, over the course of the year the DCCC is outraising the team with the big House majority.

The year-long totals show the DCCC raising nearly $48 million to the NRCC’s just over $44 million.

I think that the Republican Party Presidential Primary clown show has convinced business executives that Republicans are simply not a good investment, because while one can price risk, you can’t price uncertainty, and insane motherf%$#er teabaggers are the very definition of uncertainty.
