4 takeaways from the Nebraska and West Virginia primaries

(CNN) Tuesday's Republican primaries in Nebraska and West Virginia were a test with mixed results for former President Donald Trump 's endorsement power.
Trump suffered his first big loss of 2022 in Nebraska , where his chosen candidate for governor in the Republican primary lost to the state party's choice.
University of Nebraska Board of Regents member Jim Pillen, CNN's projected winner in the primary, was endorsed by term-limited Gov.
Pete Ricketts, and incumbent GOP Rep. Don Bacon, who had taken some flak from Trump, also won renomination.
Here are four takeaways from Tuesday night's primaries -- and a look ahead to more stress tests for Trump in the coming week.
He fell short to Pillen, but appeared to receive more votes than an alternative Republican candidate, state Sen. Brett Lindstrom.
Trump did not endorse in the race and Bacon now has a November date with CNN's projected winner in the Democratic primary, state Sen. Tony Vargas.
Trump tops Justice, Manchin in West Virginia primaryIf Nebraska mostly ignored the former President, at least for a night, West Virginia doubled down on Trump's advice.
Rep. Alex Mooney, the Trump-backed candidate in the first incumbent-vs.-incumbent primary of the year, topped Rep. David McKinley in the GOP primary for West Virginia's 2nd Congressional District on Tuesday night.
A bipartisan group of West Virginia power centers tried to save the more pragmatic McKinley, including Republican Gov.
Even still, Trump remains largely the only endorsement that matters in Republican primaries, forcing candidates, especially those in contentious races, to continue to run campaigns that appeal to him.
