Venture capitalist Peter Thiel helped get his preferred GOP Senate candidates over the hump in their primaries. So why is he holding out on them in their general election contests against Democrats?

Leaks are emerging from conversations between Thiel and Senate Minority Leader Mitch McConnell (R-KY) going back to May. Thiel had backed J.D. Vance in Ohio and Blake Masters in Arizona, each to the tune of $15 million, in their primaries. With competitive Senate races across the board, McConnell had wanted Thiel to continue financing Vance after his victory.
