I think this is a distorted view based on your conservative bias news sources.

That said, the GOP concern appears to be knowing Trump will lose against Biden, when it should be an easy GOP win if they have a "decent" candidate.

I don't need any bias conservative news source telling me what Biden has/is doing to destroy America. Heck, even CNN, NBC and other left wing sources including dem politicians are beginning to echo the same. They all see the crime waves across America, the drugs, human trafficking, the homeless, the mounting of billions of taxpayer monies being paid out for illegal aliens, cartel gangs setting up their own turfs across America, etc etc etc.
All happening under Biden.

If Trump is the front runner he will wipe out Biden. American voters were fed hoax after hoax by the democrats, the Steele Dossier, Trump a Russian Agent, Lab leak a right wing conspiracy, Hunter's laptop was Russian disinformation, the Trump's phone call with Zelensky baloney, Trump encouraged the J6 uprising, Border patrol on horseback whipping migrants.
The dem hoax list goes on and on. American voters now know better.

When American voters go to the polls come 2024 they will remember the peace and prosperity we had with Trump and the Biden/dem lies to discredit the Trump successes.

Whoever ends up being the Republican candidate for President, there will be no doubt who will win....it won't be Biden.
