Soros, Bloomberg, Steyer, and other billionaires make huge donations to Democrats to help out with Senate and House elections

It is interesting to see Senator Harry Reid complain about wealthy individuals helping out Republicans when it appears as if Democrats are getting more donations from billionaires than are Republicans.  Harry Reid should know as these donations are also going to Harry Reid's own Senate Majority PAC.  From Politifact:

We cross-checked the Open Secrets list of the top 100 individuals donating to outside spending groups in the current election against the Forbes list of the world’s billionaires and found that, as of June 19, there were 22 individuals on the Open Secrets list who were billionaires. Of those 22 billionaires, 13 -- or more than half -- gave predominantly to liberal groups or groups affiliated with the Democratic Party. The other nine gave predominantly to conservative groups. (A list of billionaires and how much they donated can be found here.) . . .

From Politico: 

STEYER: Climate-change activist Tom Steyer gave the biggest super PAC donation in this month's reports: $7.5 million to his own group, NextGen Climate. Steyer, who made his fortune as a successful hedge-fund manager, also spread some of that money around. NextGen gave a half-million dollars to Senate Majority PAC, the biggest Senate Democratic super PAC, and $150,000 to the League of Conservation Voters Victory Fund, another environmental group. 

BLOOMBERG: Michael Bloomberg is staying plenty active in his post-mayoral days. Aside from funding his gun-control-focused super PAC, Bloomberg has written checks to Senate Majority PAC and super PACs that backed GOP Sens. Thad Cochran and Lindsey Graham during their primary battles. Most recently, the former New York City mayor donated $2 million to Women Vote!—the largest contribution the EMILY's List super PAC has ever received. Only Steyer has given more money to super PACs this election season. 

SOROS: Democratic financier George Soros's checkbook has been active this summer: The prolific donor gave $500,000 apiece to House Majority PAC and the League of Conservation Voters Victory Fund. But that million dollars wasn't his family's only big outlay so far this summer. Soros's daughter, Andrea Soros Colombel, gave $250,000 to Planned Parenthood Votes. . . .
