For me, it's simple common sense and faith.
I have the common sense to see that Joe Biden is a shell of his former self and that instead of being the "leader" that the MSM is making him out to be, he is actually a follower who is being told at this point what to say and do. Case in Point - I heard yesterday him giving a speech in which you could tell he was reading (and yelling) directly form the teleprompter. I heard another version with the exact same words at a different location later in the day.
I have the common sense to see that the enthusiasm for Trump vs. the enthusiasm for Joe Biden is on a factor of a x10 to x50. Case in Point - Look at the size of the rallies for Trump vs. the dozens showing up to Biden or Harris "rallies".
I have the common sense to see that Trump's message in the final days is one of optimism in the American future; vs. a Biden/MSM message of fear and loathing of everything Trump. They have attempted to make this a referendum on Trump, which might have been effective if Trump was actually the horrible, selfish man and abject failure that the manufactured narrative has tried to depict.
I have the common sense to see the transformation of our media from informing public opinion to trying to shape public opinion. I fear that if Biden were successful, the media will stop at nothing to protect him - or - will turn on him in an instant in order to replace him with their true preference.
I have the common sense to see that the Republican party is not so very different that the party of Ronald Reagan. Many of the same themes in 1980 are still relevant and spoken of today. I also have the common sense to see that the Democratic party is in a completely different place than it was 40 years ago.
I have the common sense to see that the Democratic behavior during and after the 2016 election, during the Meuller investigation, during the runup and through impeachment, during the confirmation of Kavanaugh, and during the testimony of Bill Barr at his latest hearing is NOT the behavior I want from my public officials.
I have the common sense to see that the BLM organization is a power grab rather than an appeal for justice, that defunding police is an incredibly dangerous idea, that riots are not protests, history is important and should not be cancelled, and that the Affordable Care Act is anything but affordable.
I have the faith that enough Americans see reality as I do.
