2020 Election Live Updates: What to Watch in Today’s Primaries

Two G.O.P. Senate primaries offer — what else? — a test of loyalty to Trump.

There are, as a once promising Democrat memorably said, two Americas.

In one, President Trump is sagging in the polls, his ineffectual handling of the coronavirus and incendiary response to racial justice protests having alienated a large segment of the country.

Yet in the other America, the one where Republican primary voters will go to the polls this week in Kansas and Tennessee, Mr. Trump is not toxic at all. In fact, his endorsement amounts to a political seal of good housekeeping.

The Senate primaries in those states for seats held by two retiring Republicans have, like G.O.P. contests elsewhere, evolved into tests of who’s most supportive of Mr. Trump and critical of his intraparty opponents. Never mind that the president could be on his way out of office when the would-be senators are sworn in next year.

In Tennessee, which holds its primary on Thursday, Bill Hagerty, a private equity executive who served as finance chairman for Mitt Romney’s 2012 campaign, is running on his endorsement from the president. Mr. Hagerty helped exorcise his ties to Mr. Romney by supporting Mr. Trump in the 2016 general election and serving as his ambassador to Japan.
