When former President Donald Trump seemed to be coasting to the White House against an enfeebled President Joe Biden, the Republican Party was also sanguine about the likely results of this year’s House and Senate elections. Trump would be president, and his coattails would undoubtedly pull a few senators and representatives across the finish line, giving Republicans a workable governing majority.

But that was before the Democratic Party pushed Biden aside in favor of Vice President Kamala Harris. Where Trump was up comfortably by 3 points against Biden, Harris is now up by 2. Bigger leads in swing states such as Arizona and Georgia have also disappeared. Republicans need to face the real possibility that Trump could lose in November, as well as the real danger Harris would pose if Democrats took the House and maintained 50 seats in the Senate.
