Donald Trump has been trying to burnish his conservative credentials in his recent attacks on other Republican candidates. Despite his normal attacks on Lindsey Graham and Jeb Bush, he has now taken to attacking Ted Cruz, calling him an "ultimate hypocrite" and implying that he is ineligible to run for the Presidency.
Now it is revealed that Trump attacked current Kentucky Governor and former Senate candidate Matt Bevin. Before Bevin's victory last November he attempted to unseat Senate Majority Leader Mitch McConnell in the 2014 Senate primary.
Bevin lost the primary and McConnell went on to win in the general election. Part of McConnell's victory was predicated on outside funding.
At least $50,000 of which came from Donald Trump. Trump donated to the pro-McConnell PAC Kentuckians for Strong Leadership. The information can be found on the FEC webpage with the original document dated May 21, 2013.
How Trump's role in that election will affect his relationship with Bevin or the Presidential race is unsure. However, he had a clear opportunity to assist a Tea Party candidate versus and establishment figure and failed to do so.
