If you consider it a waste of time, don’t get involved, don’t contact and let the congressman know that you support impeaching; or if you feel strongly against it you could let him know that you are. I consider it worthwhile, as do others - about 76% of people who voted in a very informal straw poll on here a little while ago. I’ve written above in a few posts here that there’s more good to be done than just ridding the office of him, his puppet-masters, fellow-travelers, thugs, and enablers. Pursuing this on all legal fronts is a good idea - this is a very important legal front.
I agree with you on the birth issue - it definitely needs to be looked at, legitimate questions need to be answered, if the Constitution isn’t just a meaningless piece of paper. It could even be part of the impeachment proceedings, forcing a look too at things like his student records where he may have (or may not have, for all I know) been enrolled and received preferential treatment not just as a member of a protected class but as a foreign student with dual citizenship.
I didn’t say it was a waste of time. But all avenues need to be pursued. Nothing would make me happier than seeing him taken away in handcuffs. But I just don’t see the numbers just YET. In a few months’ time and a few more egregious steps towards tyranny by the Kenyan and that could rapidly change.
At least Biden would be entertaining for a few years.
