CU and McCutcheon have their greatest influence on members of Congress and State Legislators.
Spending lots of money on POTUS candidates is wasteful, the bulk of the money will be spent once each party has adopted a standard bearer.
It's then that the bulk of the money is spent, mostly by Super PACS and mostly on negative campaigns and character assassination.

Adopted a standard bearer? You mean adopt a POTUS candidate out of the primary field? The chosen candidate coming out of any convention is still a POTUS candidate, no?
Do you have any links that evidence this "CU and McCutcheon have their greatest influence on members of Congress and State Legislators."???
The Standard Bearer is the one the party selects to run for POTUS. Last time it was Obama and Romney.
I don't have links to prove CU and McCutcheon have a greater influence on the Congress and St. law makers other than Empirical Evidence.
Congress and CA St. Law Makers vote almost 100% along the party line, few members of the Republican Caucus will ever vote to increase a tax or support gun control.
In the latter instance the two members of the Colorado Legislature who supported a gun control bill were defeated in the following primary races by candidates who highlighted their support of gun control. Money from the NRA and its members had a direct influence on that defeat.
