Trump and the Koch network are the GOP's most effective endorsers by far


Measuring the effect of a political endorsement is tricky: For some voters, it may be a determining factor. For others, it may simply match previously-held beliefs. But endorsements do offer a telling gauge of how a political party's base is thinking.
For the Republican Party in 2018, endorsements from President Trump and the Koch network correlate with victory by a large margin. Nearly 90 percent of the candidates who gained these coveted affirmations won their primary this year, a FiveThirtyEight analysis finds. No other endorser can boast above a two-thirds success rate.
"That's especially interesting given the Kochs' opposition to Trump's trade policies and Trump's public feud with the brothers," FiveThirtyEight notes. Charles Koch has said Trump's principles are "antithetical" to his own, calling the president's Muslim registry proposal "reminiscent of Nazi Germany," "monstrous," and "frightening."

Also interesting is what falls at the bottom of the list. For all the present furor over the possibility of a conservative-majority Supreme Court overturning Roe v. Wade, pro-life groups Right to Life and the Susan B. Anthony List are in the bottom third of endorsers.
FiveThirtyEight conducted a similar analysis of Democrats earlier this year and found former Vice President Joe Biden, Sen. Elizabeth Warren (D-Mass.), and Democratic Party committees were the standout endorsers.
