This of course is almost the ultimate projection. The reality is trump spent the months leading up to the election informing the population that the only way he could lose would be if the evil Democrats stole another election. He put doubt in the electorate’s minds. Then he refused to accept the results of the election tried to interfere with constitutional process to stop the election process. Incited his followers to attack the capital some with the intention of kidnapping or worse Congress people and the vice president. And he has done nothing But repeat his lies sense. Meanwhile despite countless lawsuits and investigations and recounts nothing has been found to support his claims.
Nothing.

So how do you defend something like that, obviously you double down, dig that hole deeper, insist that no, the election really was stolen and Trump and his insurrectionist followers actually defenders of the constitution against evil fraudsters. In other words tell more lies. And stooges like you buy it.
