“Republicans - Learn to Fight Dirty or Keep Being Losers”
Nonsense.
The Republicans did very well in the recent elections, +15 in the House, (probably) held the Senate, won some State Houses and Legislatures.
You continue to believe the Republican Party wanted Trump to be reelected, and that they are not contesting the Presidential election because they are not fighters.
Actually, they are not fighting because they are quite content with the outcome, Joe Biden is their kind of guy.
Yes, they had to oust the interloper Donald Trump. He is not a member of the club and did not conduct himself according to their rules.
