Resistance to Trump began the day he announced himself a candidate, what are some effective methods of resisting a Biden Administration?

Refuse to make any purchases that would give tax revenue to the government. Alcohol, tobacco and even automotive services carry a special tax, including disposal fees for tires and fluids. Fuel as well has a special tax. Stick It To The Man!

Boycott future elections!!

Our resistance is our patriotism. 

If Republicans in congress can find anything to investigate him for, they will. Though it's unlikely he'll do anything stupid like dangle congressionally approved funds in front of a foreign leader in order to secure personal favors.

Hopefully Republicans return the favor ten fold and make Sleepy Joe obsolete.

It will be such a mess and disaster with socialist Democrats anyway, that America will beg for a Republican President again.

You people are silly, you knew nothing about Trump except he was on TV and wanted to get Mexican rapists the day he announced. In NYC he was nicknamed Don the Con for decades before you watched him on TV

Here's something you can try:

Resist the programs he actually stands for you disagree with. 

Stop resisting the programs you make up that you disagree with.

UPDATE: DO YOU FIND IT TELLING THAT THIS GOT THUMBS DOWN BY GOP'S?

Resistance to Trump began the day he announced because he called Mexicans "rapists" in the process. And because it was clear from the start that a failed businessman, known racist, and pathological liar would be bad choice. Which, unfortunately, turned out to be true.

Nothing or nobody can resist Joe

When he signs trade deals, producers should withhold the products they are trying to sell.
